Saturday-Sunday, May 31-June 1,
2003:
Cool and overcast
conditions with intermittent light to moderate showers on Saturday required
us to strongly limit our banding effort, and strong winds on Sunday all
but prevented banding. Consequently, our spring banding season (in
terms of effort) kind of "went out like a lamb," and our hopes for just
one more species for this spring's banding list were dashed. So,
there will be no spring banding this year of Great
Crested Flycatcher, Yellow-throated
Vireo, Yellow-billed
Cuckoo, or Golden-winged
Warbler, species (with the exception of YTVI)
that we have banded one or more of on average each spring.
.
-
Fully half of our spring banding
total of six Scarlet Tanagers was
banded on the second to last day of the season--one male (an SY bird; top
photo below) and two females, an SY and an ASY, the latter (bottom photo
below) apparently mated to the SY male. Both were caught in the same
net at the same time, and both were in breeding condition.
-
At least through Saturday we were
still catching unequivocal spring migrants, like a Magnolia
Warbler, a Mourning
Warbler, and an American
Redstart, all with large fat deposits, and
the ASY female Blackpoll Warbler
pictured below. Compared to the SY female BLPW
banded and pictured earlier in the week (for comparison, the second photo
below is another image of that same SY bird), the ASY BLPW
female had much heavier streaking on its head, throat, and sides, as well
as broader, whiter wing bars.
-
The very last bird banded for the
spring 2003 was a Northern Cardinal
that looked as though it might have fledged directly from its nest
into our nets! If we questioned whether or not today
should bring the Powdermill's spring migration banding season to an official
close, this barely flighted NOCA erased
those doubts!
Look for a full summary of our
spring 2003 banding results on this website shortly.

Tuesday-Friday, May 27-30, 2003:
Cool,
overcast, foggy and/or drizzly in the early mornings, becoming partly sunny
and mild by late morning or early afternoon every day but Wednesday (when
it remained unseasonably cool and overcast all day). Brian
Jones,
Annie
Lindsay, Jim
Gruber, Joe Schreiber,
and
Randi Gerrish helped
with the banding.
.
-
Overall, with 880 net hours of effort,
we banded 103 birds of 35 species during the first four days of the final
banding week of the spring season. The first banding day this week
(Tuesday, May 27) was by far the best day in terms of banding total (54),
species diversity (20), and capture rate (13.5 birds/100 net hours).
No new species have been added to the spring 2003 banding list so far this
week, and there are only a very few prospects in the last couple days of
the season (maybe Warbling and/or
Yellow-throated Vireo? Yellow-billed
Cuckoo and/or Great
Crested Flycatcher? Cerulean
and/or Golden-winged Warbler?).
.
-
Not unexpectedly, birds banded recently
have been a mixture of local nesting birds and later migrants. In
the first category, we banded our first fledgling Mourning
Dove (first photo below) and American
Robin (second photo below).
-
In the second category, we continue
to catch late migrant warblers like Blackpoll
(SY female pictured in top photo below) and Mourning
(SY female in middle photo below), and Empidonax flycatchers, including
our 24th Yellow-bellied Flycatcher
of the season (bottom photo below).
-
Like the SY male Baltimore
Oriole banded and pictured
here last week, an SY male Rose-breasted Grosbeak
banded today had had unsually unextensive prebasic and prealternate molts,
making it among the dullest colored RBGR
males we have ever seen at this season.
