Sightings
The regular Sunday morning (8am) Field Trip to Dyke Marsh, sponsored by the
Friends of Dyke Marsh for the last 18 yrs or so and open to all participants
met today at the picnic area to a breeze in slightly cool weather, and over
cast skies. It was a not as active today bird-wise as last Sunday, perhaps
due to the weather or the impending weather front coming upon us. Highlight
was a Common Goldeneye, spotted near the end of the trip from the boardwalk;
42 species were recorded.
We started off at the Potomac River's edge and scanned through the ca. 700
Canada Geese. We found American Black Ducks, a small group of Buffleheads,
many Mallards, 2 Pied-billed Grebes a Double-crested Cormorant and a large
group of American Coots (whose numbers today were about 400, reduced from
last week). Two adult Bald Eagles flew about and the typical 4 gull species
were easily noted. On the mudflats of Hunting Creek, 5 Great Egrets were
spotted.
The picnic area produced not one but 2 Brown Creepers giving all fine views
as they climbed tree trunks near the water's edge. In the marina area we
spotted a single Lesser Scaup - or at least it seemed like a Lesser Scaup!
This bird appeared to have faded adult male plumage of Lesser Scaup but with
a white band near the nail of the bill. Unfortunately, we did not have a
scope with us at this time, so this observation is suspect. Otherwise, the
bird had a flattish head - although not peaked over the eye - and had the
aforementioned male character. It did not hold its head up like a
Ring-necked Duck, nor have any Ring-necked plumage characteristics (or
characteristics similar to hybrids, see Mullarney et al, "Birds of Europe"
for some paintings of hybrid divers and text), and so it is thought to be a
Lesser Scaup with a slightly out of character bill coloration.
The trip down Haul Rd produced not one but 2 very shy Winter Wrens which
were quite vocal with their "telegraph-like" call notes yet maintaining
strict avoidance of visibility to the observers. Oh well!
We spotted a dozen Hooded Mergansers and then 6 Ruddy Duck in the marina
lagoon. The sparrows were thickest along the dogleg with at least 10 Swamp
Sparrows noted and even more Song and White-throated Sparrows were present.
On the boardwalk we spotted the previously mentioned Common Goldeneye,
female, off the nearby island. On our way back to the car, we got a few
drops of drizzling rain upon us, but nothing too significant.
Next week Larry Cartwright leads the last official Field Trip of the year -
Christmas Bird Counts start after that. (Of course if you visit Dyke please
send your field list to this author for addition to the FODM database.) All
are welcome to join in the upcoming CBCs - contact me if you have interest
in Dyke Marsh for Saturday, Dec 15 or helping out in the Fort Belvoir CBC
Sunday Dec 30. Thanks much!

Larry Cartwright led the regular Sunday morning Field Trip to Dyke Marsh
today, sponsored by the Friends of Dyke Marsh for about the last 18 years
and open to all comers - we meet in the picnic area by the first parking
lot. About 7 people joined today under partly sunny skies, relatively
windless conditions and jacket weather (50-60F). It was an average day for
the trip, netting about 51 species.
We started off checking the ducks in the river and noted the many Ruddy
Ducks and American Coots. Mixed in were Gadwall, Mallard, No. Shoveler, and
Bufflehead. Later on a group of Lesser Scaup few past and then a smaller
second group sat down amidst the other ducks. Whilst watching the ducks,
an Osprey hovered into view.
Haul Road produced many calling, yet hidden, White-throated Sparrows. An
adult Red-shouldered Hawk was near the marina - later we spotted a first
year Red-shouldered Hawk along the dogleg. Just before the dogleg, we heard
a Winter Wren and it was reticent to show itself (typical!). As we walked,
Northern Flickers flew past. Yellow-rumped Warblers were along the dogleg
and, near the end, many more by the boardwalk; Cedar Waxwings were also at
this location. And we actually starting seeing sparrows along the dogleg!
A White-crowned Sparrow was near the end, too. We spotted a couple of
Turkey Vultures and a Sharpie over the trees to the west. On the way back,
we heard a Rusty Blackbird near the marina. The trip list is below.

Ed Eder led the regular Sunday morning Field Trip to Dyke Marsh, sponsored
by the Friends of Dyke Marsh, meets at 8AM near the first picnic area
parking lot, open to all comers and ongoing for about 18 years.
Top birds today were the Common Moorhen (photo send to me by Ed) mixed in
with the Coots in the SAV beds just off the north picnic area. Other
interesting sightings detailed by Ed were Horned Grebe and Blackpoll
Warbler. Ed's notes are copied below. Not mentioned by Ed but seen by Jay
Keller in the early afternoon were 3 Surf Scoters, also off the picnic area.
Two of these Surf Scoters were noted yesterday.

where all are
welcome each Sunday at 8 AM in the picnic area. It was one of
those days that
felt like it was not very birdy, but the list shaped up well at the end
with 66 species.
Several species of ducks and raptors were noted, with top birds
being heard-only RED-BREASTED NUTHATCH and PURPLE FINCH, as
well as a late SPOTTED
SANDPIPER seen well by all, and a LINCOLN'S SPARROW off the
end of the boardwalk.

SightingsEight people joined me for this Sunday morning's edition of the Dyke
Marsh birdwalk. The participants included Erik Oberg who assured me that
he is still functioning as the biologist for the NPS. The highlights included
several warblers associated with small chickadee and titmouse flocks at
Dead Beaver Beach (the open area facing the water just north of the peninsula on
Haul Road) and the Dogleg (the base of the peninsula). Hummingbirds were in
aggressive mode today, with two teaming up to harass a Pewee at the Dogleg
and another two giving chase to each other at the boardwalk. A small fixed-species
kettle of raptors over the treeline south of Haul Road provided the onlookers a
good deal of satisfaction. Duck numbers are disappointing. A handfull of
Green-wing Teal flying over the Little Gut was the only non-Mallard ducks we could
find.

Sightings
A fine turn out for Sunday's Field Trip to Dyke Marsh, sponsored by
theFriends of Dyke Marsh for the public each Sunday at 8 am. About
10 people showed up for great weather and the top highlight of the day was
likely the scope views of Trail's Flycatcher in the picnic area, near the river's
edge. Classic looks could be seen by all. Another top highlight was
Boneparte's Gull, spotted by Larry Cartwright. Over 60 species were found.
We started in the picnic area and found Pied-billed Grebe, Northern
Shoveler and Blue-winged Teal relatively close by. Two Bald Eagles (adults)
were on the mudflats and many Osprey were observed. Two Eastern
Kingbirds were nearby to the aforementioned Trail's Flycatcher. Pileated
Woodpecker was briefly seen here, too. A few Lesser Yellowlegs were on the SAV
mats.Walking down to the marina we came upon a small mixed group of
migrants with Yellow-billed Cuckoo, Ruby-throated Hummer, Great Crested
Flycatcher, Yellow Warblers, Prothonotary Warblers, Northern Waterthrush, and
Blue-gray Gnatcatchers. Caspian and Forster's Terns were flying this way and
that. Another Prothonotary was on Ramp Road which gave all fantastic
looks and a few Gray Catbirds were here, too.
At the boardwalk overlook at the end of Haul Road was a Red-shouldered Hawk,
more Blue-winged Teal, our first of season Green-winged Teal launching into
flight from a marshy island and 4 Tree Swallows.

Nine people attended the birdwalk at Dyke Marsh this morning, sponsored by the
Friends of Dyke Marsh. Migrants are definitely showing up. The waters off the
picnic area were very active. The floating maps of hydrilla held several groups
of shorebirds, including a dozen lesser yellowlegs, 6 least sandpipers, 1
semipalmated sandpiper, and 15-20 unidentified peeps (too far out). Also in the
vegetation were a pied-billed grebe, 6 blue-winged teal, 3 Forster's terns and
4 Caspian terns. Along the trail we encountered several small groups of orioles

Sightings
Seven birders joined me for this Sunday's edition of the Dyke Marsh
Bird Walk.
A mild, sunny, but breezy day welcomed our group. It appears that
that some of
the passerine breeders (Yellow Warbler for example) may have
already left, but
fall migrants (Laughing Gull, Forster's Tern, Caspian Tern) are
showing up.
Ospreys put on a show, with 19 present, including 2 nests still
containing
nestlings. On a sad note, we could not find one Marsh Wren or
Least Bittern.
Marsh Wrens have been on a downward slide for 7 years and Least
Bitterns seem
to have suffered a drastic decline between 2006 and 2007.

A total of nine people turned out in typical midsummer weather for
this morning's bird walk at Dyke Marsh. No surprises, but
nonetheless a pleasant morning to be out and about before the
afternoon heat. The local Ospreys population seems to be enjoying
a successful breeding year -- the birds were flying all over the place
up and down the river. Both species of orioles had young begging to
be fed. While we only got a brief view of a Prothonotary Warbler,
another birder reported seeing three of them. The complete list
appears below.

Belated report from Dyke Marsh - Alexandria - glad some folks were able to
try for the Seaside Sparrow - Kurt Gaskill tells me that they breed along the
Potomac to around the Rappahanock River, so it didn't disperse as far as I
thought it might. A great spot by Rusty at the end of the boardwalk!
Some other fine birds include the now 2 American Wigeons that were dabbling
w. the mallards at the north end of the picnic area. Peter spotted us a Black
and White Warbler as we started down Haul Rd. and it was looking somewhat the
worse for wear. We spied a fledged cowbird being fed by a Carolina Wren and
Peter and Rusty picked up a fledged Yellow Warbler being fed by an adult male.
One Least Bittern gave us nice looks in the Little Gut. At least 2 Great Egrets
were present and an early stop by the mud flats produced 2 Killdeer and 3 Wood
Ducks. Ed Eder reported a Spotted Sandpiper that eluded us and also Brown
Thrasher w. young near the wood bridge on the peninsula. We missed the young
'uns, but got to see one adult.

Sightings
Wonderful cool temperature, low humidity, mostly blue skies and slightly
breezy conditions met about 10 participants to the Friends of Dyke Marsh
Sunday morning Field Trip, free to all and we meet at 8AM in the south
picnic area. Top bird was a male American Wigeon. Certainly not unknown in
the summer, but not often seen in JULY! I suspect it's the same as the one
observed a few weeks back in the same place - Hunting Creek Bay, between the
picnic area and the Stone Bridge.
Birds were quite active and we had a grand time watching them come and go in
the picnic area. Young Orchard Orioles were clearly on the wing, following
adults back and forth. An Eastern Phoebe hunting over the water in the
picnic area; probably a dispersal bird as the species does not breed at
Dyke. But House Wrens appear to be feeding young in the nearly dead tree in
the south central picnic area - the cavity is near the top of a vertical
limb stub. Eastern Kingbirds were also quite conspicuous in many locations
from the picnic area and along Haul Rd; all were amused during one instance
where 2 kingbirds ganged up on a Fish Crow. Osprey young are getting quite
big now and parents were doing a lot of fishing to keep up with the growth.
A single Prothonotary called from the woods next to Ramp Road but it would
not pish out. And a Gray Catbird is still in this same location. Down the
trail we heard an Acadian Flycatcher in the woods and later a pair of
Red-eyed Vireos - apparently adults. Only one faint Warbling Vireo was
heard in the woods just south of Dead Beaver Beach. Viewing from said beach
we could see Tree Swallows bringing food to a nest box - on a moored
sailboat! We suspect the Common Yellowthroats are nesting near the trail by
the dogleg bend - a singer was in the woods and a calling bird in some
nearby bushes. On the way back, a single Baltimore sung once along the
trail. And near the parking lot were a mixed group of chickadees and
titmice where the titmice were mostly juvies, some still showing gape
coloration.

Sightings
Another beautiful morning for the weekly Dyke Marsh walk. The
highlight was least bittern, which was unusually cooperative. From the platform at
the end of the boardwalk I found a brightly-colored one hunting on the mud
along the edge of the water (tide pretty low). I got it in the scope and we all got
great looks. It eventually flew out of view, and later we saw the same
one(?) fly over the marsh and drop into the grass. A little later we saw a rather
plain-looking least bittern flying over the grass, joined by a more
brightly colored bird. Rather than quickly dropping into the grass, they kept
flying until they disappeared behind some trees.
Other items of note were 4 each of baltimore and orchard oriole, with
one of the baltimores a young bird being fed by an adult. We saw a
goldfinch working on a complete-looking nest. Warbling vireos appeared to be absent
from the picnic area, but two males were loudly singing past the dogleg. All
the osprey nests appeared to be holding multiple large young. We heard at
least 2 marsh wrens singing from the grass, and I heard a house wren from the
picnic area. We also saw a brightly colored parrot in the marina.

A wonderful clear morning that was coolish to start but started warming up
to late June temperatures near the end. And a typical Field Trip at Dyke,
sponsored by the Friends of Dyke Marsh and free to all (meet at 8am near the
first parking lot). The theme from last week was continued as more species
were going silent early in the morning, after singing for a bit. We managed
to see 3 different Orchard Orioles but heard only one Baltimore. The
grackles, starlings and robins were out in force and juveniles were evident.
A young Northern Mockingbird was on its own in the picnic area. Eastern
Kingbirds were found in several places - one good spot was the mulberry tree
near ramp road and the bathrooms which attracted several other birds
including a pair of Gray Catbirds. The main picnic area hosted a pair of
House Wrens - unusual at Dyke as 15 years of breeding bird surveys have yet
to produce a pair until today!
Osprey young are getting bigger - the nest near the boat ramp is a
photographer's delight and the young are already bigger than any passerine.
Keep up the good work! A few Mallards and Canada Geese were seen in Hunting
Creek Bay and the passages in between the islands off the marina - one such
passage held a nearly full grown Mallard with mom. We saw many Great Blue
Herons but no sign of Least Bitterns this time. Common Yellowthroats seem
to setting up house near the dogleg in Haul Road. The House Finch in the
Sycamore near the bridge along the dogleg nest appears to be occupied. And
the end of the dogleg at the board walk produced 4 Northern Rough-winged
Swallows hanging out in the bear branches of a tree.
Earlier in the morning, point counts along the bicycle path produced
Prothonotary Warbler, more orioles of the Orchard and Baltimore persuasion,
Acadian Flycatchers, a Red-bellied Woodpecker carrying food, and a Pileated
Woodpecker.
All in all a typical summer day of breeding at Dyke! - Kurt Gaskill - June 17, 2007.
Sightings
Notwithstanding the closure of the Geo. Washington Parkway for a
race, a total of 15 people turned out on a beautiful sunny morning for the weekly
Sunday bird walk at Dyke Marsh. A total of 47 species were seen. The highlights
were a Horned Grebe which flew in and landed right in front of us as we
were beginning the walk, nice lingering flocks of Ruddy Ducks and Red-breasted
Mergansers, and a sole Yellow-throated Warbler showing off in the sunlight. A pair of
Hermit Thrush kept leapfrogging each other as we moved down the path.
Yellow-rumped Warblers and Blue-grey Gnatcatchers made themselves
conspicuous -- a pair of Gnatcatchers have a nest underway right where the path makes a
dogleg to the left. The complete list appears below.

Only two folks joined me for today's edition of the Dyke Marsh walk. Evidence
of spring was all around us despite the windy conditions. We found one Eastern
Phoebe in the parking lot and a second on Haul Road. One Dark-eyed Junco (not
normally a wintering bird at Dyke) was foraging in the picnic are. The river
hosted three Horned Grebes, Wood Ducks (3 pairs and a singleton), and small
numbers of Common and Red-breasted Mergansers, Buffleheads, Canvasbacks, and
Lesser Scaup. Song Sparrows were everywhere. We observed a Hermit Thrush and a
perched Tree Swallow and heard an Eastern Towhee just south of Dead Beaver
Beach. Bonnie Ponwith conjured up a half dozen Killdeer in the marsh.
Five Osprey nests are now occupied.
1. The nest on the platform at Port O'Vecchio contained one bird
2. The nest on the pilings in the channel contained one bird
3. The nest at the marina is under construction with one bird carrying sticks
to the nest site
4. The nest at the root site on the island adjacent to the marina is under
construction with a bird ferrying sticks to the nest site
5. A new nest is under construction on the island south of the platform at the
End of Haul Road. This replaces the nest that was lost last July when heavy
winds blew down the snag hosting the original nest.

Seasonably weather this morning at Dyke Marsh - that is, if you discount the
strong wind from the north! The wind made it chilly but the birds continue
to do their thing. An Osprey was reported carrying sticks to the Hunting
Creek Bay nest site. Three Osprey sites were occupied with an Osprey
sitting in last year's nest - the aforementioned Bay platform, the Port
O'Vecchio site, and the root site near the marina. Another Osprey was
spotted near Pipeline Bay. The cold wind did not stop the Tree Swallows as
several were spotted flying back and forth near the shoreline. A good duck
show with many divers coming close to the group for good looks (fortunately,
we had a scope for some of the other, more distant, looks!). Highlights for
this group were Gadwall (8), American Wigeon (18), Redhead (4), Bufflehead
(6) and Common and Red-breasted Mergansers. Plus 3 Horned Grebe with one
displaying obvious plumage change. As we started down Haul Road we were met
by a single Rusty Blackbird which came in pretty close - about 20 feet near
eye level. We all got fine looks at various Song Sparrow plumages as this
species was foraging along Haul Road along nearly its entire length. And as
we were scanning waterfowl from the first platform a migrating Eastern
Bluebird was heard. After the Field Trip - sponsored by the Friends of Dyke
Marsh and open to all comers every Sunday at 8AM - I went to the Hunting
Creek mudflats to check on gulls. No unusual gulls but there was one Field
Sparrow singing at the little wetlands by the apartment building. The day
ended with 50 species tallied.
By the way, since the Osprey activity signals the beginning of the breeding
season at Dyke Marsh, let me note that Friends of Dyke Marsh conduct a
breeding bird survey at Dyke. This will be the fourteenth year that the
survey using full BBS protocol employed will be done. Volunteers are always
welcome. Contact the coordinator, Larry Cartwright (prowarbler@verizon.net) for more information. By the way, this is a brilliant
opportunity to paddle a canoe into the marsh and find Marsh Wrens and Least
Bitterns! New birders are ALWAYS welcome! Kurt Gaskill - March 11, 2007.

A cold morning with little or no wind - 17 F (-8 C) and lots of ice greeted
a small turn out today (up to 5 at one point) for the regular Sunday morning
Field Trip to Dyke Marsh, sponsored by the Friends of Dyke Marsh and free to
all. The day's highlight was the obvious (and seasonal) build up of Common
Mergansers on the Potomac; we estimated about 500 birds. The Bald Eagles
were down from last time I was here, 2 adults and 3 immatures. Close in to
the picnic area was the open water channel flowing out of Hunting Creek and
this attracted many Mallards, 2 American Black Ducks and the typical 3 gull
species. More American Black Ducks were out off the mudflats. Our trip down
into the marina netted our first look at a first cycle Red-shouldered Hawk
plus Bufflehead and Red-breasted Mergansers. The walk down Haul Road was a
constant feast of close in sparrows, including the leucistic (partially
white-headed) Song Sparrow that allowed us to get as close as 12 feet. A
single Gray Catbird called along the trail, and a couple of Winter Wrens and
Ruby-crowned Kinglet were along the first half of the trail. A surprise
just north of the dogleg was a Hermit Thrush - never common at Dyke. Along
the way we were met with many Red-winged Blackbirds singing "kok-a-lee";
northbound migrants that were putting in some practice on territory songs. A
single Common Grackle - another northbound bird - was near the bike trail. The
end of the trail near the boardwalk brought us more ducks and two Red-tailed
Hawks. On the way back we spotted a Fox Sparrow by the little bridge on the
dogleg. After the trip I checked the mudflats by the Stone Bridge and added 2
Killdeer. The list of today's 47 species follows.

Sightings
Winter's mild touch came upon Dyke Marsh this morning where 6 birders met
for the weekly Sunday Field Trip (starts at 8am and free to all) - a chill
wind from the north caused us to break out the gloves for the duration. We
started off in the picnic area to a grand Bald Eagle show with about 10
immatures and 8 adults noted, most over the nearly frozen river-side
mudflats - and from that point on hardly 5 minutes would go by without
spotting a representative. Very Nice! This is one of the larger counts of
Bald Eagles at Dyke and certainly the largest during the month of January.
Could the cold weather have driven them to Dyke? Or have these been held up
from their northward travels by the cold front? Or has the local population
grown so that immature birds are just more common in these times? Whatever
the case, 2 adults were seen on/near the nest near the Wilson Bridge,
Maryland side.
We walked the river's edge to the marina and found very few passerines - the
wind must have swept them into the interior of the preserve. Red-breasted
Mergansers were easily found on the Potomac. A large group of Canada Geese
could be seen far to our north against the shoreline near the Stone Bridge.
A few scattered Bufflehead were more in the middle of the river. A pair of
Pied-billed Grebes was inside the marina bay area. Here we saw our second
Belted Kingfisher; all today appeared to be males.
Our walk down Haul Road produced many sparrows - Song and Swamp Sparrows
were evident in larger than usual numbers along the trail suggesting the
recent cold had sent them - we tallied 65 Song and 14 Swamp Sparrows for the
day. Only a few Red-winged Blackbirds were noted and just a single Winter
Wren was observed. We did chance upon a perched adult Cooper's Hawk which
presented scope views. Later, when it moved, the Blue Jays put up their
alarm calls. Near the dogleg, a large group of Song Sparrows eventually
produced a fleeting glance at an American Tree Sparrow - unfortunately not
long enough for Ed Eder to unholster his camera! But the Gray Catbird came
out and stayed visible for several minutes both on our first pass and then
on our second pass as we retraced our steps to the car. And a Brown Creeper
was spotted here by the keen eyes of Sandy Farkas. The remainder of the
trail produced more sparrows, both Golden-and Ruby-crowned Kinglets and more
views of waterfowl on the river including American Black Duck (close in to
the marsh), Common Mergansers, a single Hooded Merganser and many Lesser
Scaup. We noted a half dozen Great Blue Herons huddled on the island off
the end of the boardwalk and an adult Red-shouldered Hawk flew out from the
island and over our heads at trail's end.
After the trip, Sherman Suter and I visited the Hunting Creek mudflats at
the Stone Bridge but did not turn up anything unusual, although we tallied a
new species for the day with 7 Killdeer foraging over a section of unfrozen
mud. We netted 48 species at Dyke today. Kurt Gaskill - January 21, 2007.
Sightings
Five birders joined me for today's edition of the Friends of Dyke Marsh. The
day started poorly, but got progressively better, and the sun even briefly
appeared. Highlights were 2 Singing Fox Sparrows and a Field Sparrow near the
dogleg, 2 singing Winter Wrens on the peninsula near the boardwalk, and 9 Bald
Eagles (5 immature and 4 adults). Duck numbers are still low. Perhaps the front
pushing through this Tuesday will bring more birds to our area. Nothing really
noteworthy, but it was nice to see a fine assortment of sparrows. And Downy
Woodpeckers and White-breasted Nuthatches seemed to be everywhere!

The first of the new calendar year Dyke Marsh Field Trip took place today
with nearly a dozen folks in attendance, and relatively mild January
weather. The highlight of the trip was a Peregrine Falcon perched on a low
branch stuck into the Hunting Creek mudflats (river side) first thing. We
also noted 4 Bald Eagles - all adults and two of which were perched in the
Maryland/Wilson Bridge nest. Red-breasted Mergansers put on a fine display
in Hunting Creek Bay as well as near the end of the board walk - great scope
views were had and their red eyes were easily seen! The walk down Haul Road
was mostly uneventful, both kinglets showed up and a Red-shouldered Hawk
perched on a tree on one of the islands. And over flying Gadwall was noted,
a couple of Bufflehead were in the river, a good-sized kettle of vultures
were noted over Maryland, a couple of north bound DC Cormorants were spotted
(huh?), a single Pied-billed Grebe off the boardwalk was observed and at
least 8 Winter Wrens were tallied, including 2 that actually showed
themselves for a sum total of 5 seconds and one singing. We tallied 40
species for the day.

All three merganser species were present during the walk, including 3 Common
Mergansers reported by Kurt Gaskill. Both species of kinglets were observed and
these little dynamos put on quite a show. We also had great views of
Red-shouldered Hawks. Besides the kinglets, other winter visitors, including

Seven people joined me this morning for the regular Sunday Field Trip at
Dyke Marsh. It was a gorgeous day, bright blue skies and only a little on the
cold side. But there was nothing exceptional on the birding front. No vocal or
visual signs of the ten Winter Wrens noted last week, though the habitat is
just fine for them; I am sure there must have been some still around. Ditto for
the Fox Sparrow. But we did see quite a few Swamp Sparrows, including one
that sat up brilliantly for quite a while, giving one of our number a splendid
life bird.

The immature Bald Eagle: First spotted in bare trees near the new bridge,
Virginia side, very close to an adult bird. Later they were seen from the Stone
Bridge on two small 'bushes' in the mud flats, with the adult later coming
to the same 'bush' as the immature bird. Observed eventually at 500 yards
under 45 power telescope.
Size of the immature bird was equal to the adult, and they were clearly
"together".
The head of the immature bird was patterned like an Osprey, except that the
'white' bits were medium gray. The back was fairly typical: brown with many
flecks of white. The throat and upper breast appeared to be solidly dark
brown, with only a few small flecks of white; the lower border of this area was
a deep zig-zag. The strangest part was the lower breast and belly: clear white,
but dotted all over with black, which reminded me of a Martial Eagle. No
details of the tail could be seen. Stephen Eccles, December 3, 2006.
Sightings
Eight people joined me for the regular Sunday morning Field Trip at Dyke
Marsh, sponsored by the Friends of Dyke Marsh and free to all. We started
in some medium morning fog which burned off into a beautiful day with light
breezes from the south. Top bird was Fox Sparrows: two of which perched up
nicely for all to see at close range - the first along Ramp Rd and the
second along the beginning of the dogleg. There was a third Fox Sparrow
singing brief stanzas of its song near Dead Beaver Beach.
We started out in the picnic area - now mostly bereft of leaves except for a
few bushes. Birding began with kinglets plus a couple of juncos -
curiously, juncos are never common at Dyke; the relative lack of conifers
for roosting may be the reason? Our scan of the Potomac produced only
Mallards plus the 4 typical gulls and a few DC Cormorants. Fortunately, Ray
Smith snatched a male Lesser Scaup out of Maryland waters to improve our
waterfowl list (good hands Ray!). Two adult Bald Eagles on the mudflats and
2 more found as the day wore on. Brown Creepers were also present in the
picnic area and all got fine looks of at least one. Belted Kingfishers put
on a good show starting from the picnic area and continuing through the
marina and then at the end of the trail on the boardwalk deck - including a
pair dueling over winter fishing rights. An immature Red-shouldered Hawk
near the marina got scope looks by all. More kinglets were observed along
Haul Road plus a single Yellow-bellied Sapsucker that was seen by a few.
Haul Road produced a good number of Winter Wrens - 10 in all - including 2
that broke out into song and a couple that actually SHOWED themselves!
Excellent numbers of White-throated Sparrows along the trail, too. As we
got to the marsh edge, we encountered many Swamp Sparrows. The trees held
finches -red and gold were the colors, plus Red-winged Blackbirds. At
trails end we added 2 Pied-billed Grebes near the island, had a flyby and
southbound Forster's Tern go past at arm's length, and, as we retraced our
steps to our cars, a Turkey Vulture popped up overhead.
I finished my day at Dyke counting gulls at the Stone Bridge near sunset -
the tide was lowish. Laughing Gull numbers were about the same at
Ring-billed Gulls - I tallied ca. 1350 each. Also there were 3 surprises -
a fourth year Lesser Black-backed Gull, 2 male Bufflehead and a Red-throated
Loon. I tried to convert the loon into something more conventional or even
unconventional, but the dainty upturned bill and lack of chin strap stopped
me. The latter is a fine and unusual bird in our Northern Virginia area.
The species total was one shy of fifty. Kurt Gaskill November 26, 2006.
Sightings
Six birders joined me for this Sunday morning's version of the Dyke Marsh walk
(southern Fairfax County). We had great views of Bald Eagles, hunting
accipiters, and a Red-tailed Hawk. Cedar Waxwings and American Robins feasted
on poison ivy berries. Flyover Tundra Swans delighted the group. The big
disappointment is that there are still virtually no ducks present.

A fine day at Dyke Marsh for 6 visitors during the regular Sunday Field Trip
at Dyke Marsh, sponsored by the Friends of Dyke Marsh and free to all.
Having great looks at a migrant flock in the picnic area was everyone's wish
and it was granted with a group near the boat ramp mostly coming down to the
20 foot level that left everyone pleased. We sat on a picnic table and
watched the them - first the Black-throated Greens. Then this Blackburnian.
The Black & White and Magnolia's stayed in the back ground. But the
Blackpolls came right down showing faint, blurry streaks on off-white
breasts. Then a Yellow Warbler came by - muted almost to a yellow-green all
over which Dunn indicates is the subspecies "amnicola". A Chestnut-sided
soon came down and showed all its lime-green back. A couple of
Yellow-rumped Warblers were present. And here and there were a few Northern
Parulas. All of this with a background of Forster's Terns diving nearby,
Bald Eagles flying about, huge groups of Laughing Gulls flying overhead, and
the usual Dyke Marsh woodpeckers (all the typical year-round ones were
seen), American Robins, etc.
Down the trail a few more warblers showed themselves, we spotted a calling
Swamp Sparrow, noted Coopers, Red-shouldered and Red-tailed Hawks. We also
spotted Red-eyed Vireo and Eastern Wood Pewee (and one of the latter was
singing). A Virginia Creeper high up in a tulip poplar attracted many
American Robins to its berries and to the delight of all one Gray-cheeked
Thrush! House Wren and Common Yellowthroats along the dogleg plus
Pied-billed Grebes and Green-winged Teal added to the day's lists. We noted
a few Turkey Vultures which obligingly flew across to Virginia and kettled
up over the picnic area. And Ed Eder told of us of a few Ruddy Duck at dawn
near the boar ramp. All told, the Field Trip netted 63 species.
Afterwards, I visited the Stone Bridge to add in a few species and check out
the shorebirds. The payoffs here were many Killdeer, Greater Yellowlegs, a
Pectoral Sandpiper with a bum leg, and 3 White-rumped Sandpipers.
What will next week bring?

Several participants showed this morning for the weekly Dyke Marsh bird walk,
and things were pleasant until we hit Haul Road. If you go to Dyke Marsh,
please prepare yourself with lots of insect repellant. Those that had it were
fine, while those of us that did not had a difficult time.
Few species of migrants were about, but there were several good birds to keep
it interesting. There were two PIED-BILLED GREBES - one off the picnic area,
the other off the end of the boardwalk, a continuing MARSH WREN chattering, a
returning SWAMP SPARROW, and five BALD EAGLES of varying ages perched on the
mudflats at low tide.

Five of us enjoyed the weekly Dyke Marsh bird
walk, and were pleased to get a
respite from the recent hot weather with today's
temps not exceeding the
mid-seventies. Top birds were a LEAST TERN observed flying
south off the boardwalk area, and
two LEAST BITTERNS (one heard, one seen flying
across the open water), a couple
of FORSTER'S TERNS in the same area, and a
displaying MARSH WREN at the nest
near the footbridge on Haul Road.
I was not able to scan the mudflats after the walk
(high tide was before the
walk), so there were likely more Larids and possibly
some shorebirds in
addition to the SPOTTED SANDPIPERS and
KILLDEER seen off the boardwalk.
Several juvenile birds were observed today,
including BROWN THRASHER, GRAY
CATBIRD, and YELLOW WARBLERS among others.

Five birders braved a hot and humid day to join me
for today's edition of the
Dyke Marsh Sunday morning walk. It was rather
slow with disappointing misses,
such as Baltimore Oriole. However, it wasn't a total
wash. Highlights consisted
of a fledged Great Crested Flycatcher fledgling
being fed a preying mantis by
an adult in an area Jay Keller and I felt a nest might
be located during the
breeding bird survey, and 4 active Osprey nests
with an accumulated total of 8
nestlings. Kurt Gaskill reported Forster's Terns
yesterday, but we only came up
with a solitary Caspian Tern. Although most
songbirds were silent, 3 Warbling
Vireos persisted in song, 1 in the picnic area and 2
on the Haul Road peninsula.

Sightings
The regular Sunday morning Field Trip to Dyke
Marsh, sponsored by the
Friends of Dyke Marsh, was met by sunny skies
and moderate morning
temperatures with little or no wind. The highlight of
today’s Discovery
were at least 2 Gray-cheeked Thrush singing near
the Haul Rd trailhead, and
2 Swainson’s Thrush nearby. Many got good, but
fleeting looks at these
birds (will they stay for the morrow?). Earlier,
Sandy Farkas and I had
visited this same spot and, after much studying of
bird song CDs, I conclude
there was also a Bicknell’s Thrush in this same
location earlier (about
0645) – the clincher being the low chuck notes
before every other phrase of
the Bicknell’s song which ends on flat or upward
notes (listen to your tapes
and you will hear them, also see the brief note in
Jonathan Alderfer’s new
book, “Complete Birds of North America”; there was
also an upslurred call
note from another location later)
Other highlights were 2 Yellow-billed Cuckoos one
near the dogleg bend and
the other just 200 yards down from the Haul Rd
trailhead. We got fine, but
distant looks at a pair of Great Crested Flycatchers
near Ramp Rd, and we
counted 5 Warbling Vireos and saw 2 of them (4
locations, the boat ramp,
half way down Haul Rd, and two on the dogleg).
We noted at least 8 Red-eyed
Vireos along Haul Rd (still migrating), 2 Marsh
Wren, an empty Blue-gray
Gnatcatcher nest on the dogleg (fledged I would
think), 2 pairs of Yellow
Warblers on the dogleg and a single on the island
near the marina, a calling
Prothonotary Warbler on the Haul Rd about 250 yds
south of the trailhead
(this one was a surprise, not a good habitat), a
Black & White Warbler
spotted by visitors from Louisiana, and 3 singing
Song Sparrows (marina,
dogleg bend, and half way down Haul Rd).
Everyone got fine looks at various
Orchard and Baltimore Orioles and we saw two
nests that were apparently
abandoned (?).
Before the Field Trip and near the end of the day I
checked a few spots and
found a dozen Wood Ducks near the Stone Bridge
and a Peregrine Falcon
strafing gulls on the river side mudflats, 27
Semipalmated Sandpipers (no
sign of yesterdays Dunlin), a couple of Laughing
Gulls, 4 Caspian Terns, and
Prothonotary Warbler where the bicycle trail
crosses the gut.
The combined totals are listed below to give you an
impression of the birds
at Dyke this last Sunday of May.

Sightings
At least 45 people joined me for this Sunday
morning's edition of the Dyke
Marsh walk. Today's highlights were a vocalizing
Black-billed Cuckoo (a good
migrant at any location), a singing Yellow-throated
Warbler (a bird that
already should be breeding at Leesylvania, Mason
Neck, or Riverbend- they are
not recorded as breeders at Dyke), a well-observed
American Bittern, and an
even better-viewed Least Bittern, both seen on the
mud flats across from the
end of the boardwalk. We heard a lone Marsh Wren
at the same location. There
are 6 active Osprey nests, a pair of Barn Swallows
nesting on a boat at the
marina, a pair of Tree Swallows in a nestbox
erected by Chip Johnston and Kurt
Gaskill off of Haul Road, an Eastern Kingbird nest
in a Sycamore south of Dead
Beaver Beach, and Blue-gray Gnatcatcher and
Baltimore Oriole nests on the Haul
Road peninsula (the former providing great views of
an incubating female). We
also witnessed the harshness of nature- a Black
Rat Snake depredating a nest
cavity full of Red-bellied Woodpecker nestlings.
Warbling Vireos were found in
the picnic area and the Haul Road. Last year's
breeding bird survey data
indicates the number of breeding pairs may be
increasing, although we do not
reach the safe date for this species until June 10.
The walk was a great time,
but the large crowd did make for some confusion. I
want to personally thank
Sandy Farkas and Henry Brooks for providing
services as co-leaders. It made my
job much easier. Now the complete list provided
below.

This morning several birders spent a delightful morning beating the bushes for
all Dyke Marsh (Fairfax County) had to offer. Top birds included: a very close
fly-by of an AMERICAN BITTERN at the end of the boardwalk as it flew into the
nearby marsh, a vocal and bright male WILSON'S WARBLER of which everyone got
great close-in views, MAGNOLIA WARBLER at the beginning of Haul Rd, WARBLING
VIREOS, and two NORTHERN WATERTHRUSHES. A small mouselike tan-colored bird that
flew into some marsh grass just off the boardwalk may have been the
previously-reported Sedge Wren, but the look was not sufficient and it was not
calling. The morning's list follows - 70 species.

We led the Dyke Marsh field trip this morning. Five other birders joined us
for a good day out. Highlights were 1 Common Loon, 1 House Wren, 1 Gray
Catbird, 1 Rusty Blackbird and 1 immature White crowned Sparrow. We also
had 1 small Canada Goose that may have been a Cackling. The bird was about
1/3 smaller than the Canadas around it, Mary Alice was able to get a look at
the bill and thought it short and stubby. We are leaving it as
un-identified though as it could also be just a small Canada.
An obliging Red shouldered Hawk and Bald Eagle posed well for the

A beautiful clear day made for many nice bird sightings. At the head of the trail, an American redstart was singing and displaying among the tangle of vines and bushes. An orchard oriole was singing high in the top of a locust tree. Blue-gray gnatcatchers were abundant. Yellow warblers were seen near the end of the trail after the bridge crossing as well as a male Baltimore oriole and a yellow-billed cuckoo. Caspian terns were feeding in the water and two loons were floating several hundred yards offshore. Although never spotted, an Acadian flycatcher was singing in the woods and several fluttery blurts of a great crested flycatcher were heard high above. Back in the parking area, in an isolated shade tree, we spotted what appeared to be a warbling vireo, suspected to be such by its song which sounded similar to a house finch. May 1, 2005 - Joe

As it was a gray, somewhat drizzly afternoon, there was almost no human activity on the bike/hike trail as I walked through Dyke Marsh. At the southern end of the Preserve, just north of Wellington, I came around a curve to find two red foxes standing in the trail. It appeared to be an adult and its offspring. The youngster went immediately into the dense undergrowth while the adult and I stared at each other for about twenty seconds. I did my staring from about 100 feet away with my binoculars. The fox then slipped away into the brush and left the trail for me to pass by. Sunday, April 24, 2005. 4:00 p.m. Tom.

SightingsLocated a yellow warbler nest along the trail. It's about 40-45 feet before the first bridge. If you are facing the bridge, it's on your right-hand side and about 6-7 feet high on a smaller branch above the shrubbery. The female had not yet laid her eggs (although we haven't been back since) but the pair was quite busy preparing.
