November 24-30, 2003:
The 2003 fall banding season at Powdermill drew to slow close over Thanksgiving
week, with just 61 birds of ten species banded (but with many birds, or
at least many bites, of one species gobbled down!) We hope that our
fellow banders were satisfied with their own fall banding results and that
everyone was satiated by their own holiday repasts! We will
try to write a full summary of our fall banding season within the next
few weeks.
.

Although we probably have set no
banding records this fall, we did reach a significant milestone for this
banding website in the last week of the fall 2003 banding season, when
it received its millionth "hit!" This website was launched in September
2000, and we are very gratified that increasing numbers of banders, birders,
and others have found it to be a useful source for information, images,
and ideas. Our sincere thanks to all of you for your interest--we'll
do our best to keep you coming back for more!

The most commonly banded bird in
the last week of Powdermill's fall 2003 season was American
Goldfinch (33 banded), followed by
Dark-eyed Junco (9). One notable banding
result during the last week of the fall season was the capture and banding
of four (!) Red-bellied Woodpeckers,
three on 11/28 (only the second time we've ever banded three of this species
in one day) and one on 11/30 (with two more caught after the season on
December 4). Even non-migratory birds, like RBWO,
undergo seasonal movements, including dispersal of young birds away from
their natal territories, and expansion of the home ranges of adults to
gain access to more food resources (e.g., bird feeders) in winter.
.
Breakdown of the age and sex
classes for the six recently banded RBWOs
was three males and three females, and three HY birds and three ASY birds.
Pictured below is one of two HY males (top bird, with a red crown) and
the single HY female (bottom bird, with a gray crown) banded in the last
week of the season.

November 12-23, 2003:
Our banding activity during the last two weeks has been minimal.
One reason is that we are in the midst of some extensive habitat management
(something we try to do every several years to keep habitat in the net
lanes as consistent as possible from year to year), which has limited our
use of nets around our small pond complex. Another reason is that
the weather has been either too nice to catch many birds when we have had
nets open (i.e., unseasonably warm and sunny weather, with virtually no
activity at our bird feeders) or too inclement to open nets at all (extremely
strong gusting winds and or heavy rains)! As a result, we haven't
kept our loyal volunteers--Randi Gerrish, Carole Shanahan, Annie Lindsay,
Carroll Labarthe, and Brian Jones--very busy lately.
.
-
Torrential rains on Wednesday caused
extensive flooding in the banding area, precluding any banding...
...but making fishing easy!
Powdermill's Mike Lanzone grabbed
this largemouth bass from the waters
of our flooded driveway and
returned it safely to Crisp Pond.
-
We banded our first American Tree
Sparrows on 11/16 and 11/22.
-
Our last bird to band during then
period covered by this update was our eighth Sharp-shinned Hawk of the
season on 11/23, a pale yellow-eyed, streak-breasted immature male.
Brian Jones banded it (top photo), Annie Lindsay processed it (next two
photos), and we succeeded in getting a dramatic photo as Brian released
it (bottom photo) on this beautiful Sunday afternoon.

October 29-November 9, 2003:
The pace of fall banding slowed greatly during the last week of October.
Nonetheless, we appreciate volunteers Randi Gerrish, Carroll Labarthe,
Mary Helen Chiodo, and Brian Jones, all of whom helped with the banding.
Our only fairly busy banding days during the period covered by this report
occurred back-to-back on November 6-7 and were the product of fairly large
catches of White-throated Sparrows
and American Goldfinches
(61 of the former and 77 of the latter over the two days).
.
We banded three immature
White-crowned
Sparrows
on those same two days, one of which
gave us an initial impression of possibly being the western "Gambel's"
subspecies (bird on right in photo below with light lores, banded on 11/6)
but which we eventually decided probably was an intergrade between Gambel's
and the typical dark-lored eastern race (bird on left in photo below, caught
the next day). The lighter lored bird banded on 11/6 lacked the yellow-orange
bill coloration seen on the more clearcut Gambel's that we banded last
fall (second photo below).
-
We banded our fourth Yellow-bellied
Sapsucker of the season on 11/1, a hatching
year (HY) male (incoming red throat feathers mixed with retained brownish
head and breast feathers).
-
Although they have been present
in the banding area in flocks numbering several hundred birds, we have
not had any very big catches of Cedar Waxwings
during this late fall period. A few caught recently were all adults
in late stages of their definitive prebasic molt. Most, like
the bird pictured below, were molting "wax to wax," meaning that the old
(not yet molted) secondaries had large wax tips, similar to the wax tips
on the recently molted or molting secondaries. In the photo below
from left to right are freshly molted tertials (i.e., secondaries) 8 &
7, unmolted (but wax-tipped) secondaries 6 & 5, molting (<1/4 grown)
wax-tipped secondary 4 (mostly hidden behind unmolted s5), and molted,
wax-tipped secondaries 3 & 2. Because hatching year (HY) CEDWs
ordinarily have no wax tips on their juvenal secondaries, or else very
small and thin wax tips, adult CEDWs
that are replacing old prominently wax-tipped secondaries with new wax-tipped
secondaries are known after second year (ASY) birds (i.e., SY birds would
be molting "no wax to wax").
