First fall capture for Eastern
Bluebird (an immature, or HY, female: note
molt limit between the two brownish retained juvenal outer secondary coverts
and the molted blue-gray innner sec. covs.)--out of about a dozen bluebirds
circling around a nest box placed at the edge of a small pond
near two of our nets, only one was caught (two others were caught in nets
briefly but quickly escaped)

We banded 57 American
Goldfinches, our highest daily total so far
this season--adult (AHY) male (top) and female (bottom)
in typical "Definitive Basic" (i.e., adult winter) plumage are
pictured below. During the so-called prebasic molt of both adult
males and females, most of the bright yellow body feathers from the "Alternate"
plumage, worn in spring and summer, are replaced in fall
with more dull-colored feathers. Most adult males will still have
a bright yellow "shoulder" patch after the prebasic molt
(although, rarely they may lack it), while immature (HY) males usually
do not acquire one, at least not a complete one, until their second fall.

We want to publicly acknowledge Laura Quattrini,
our fall banding assistant, for her excellent
work from August through October. Without her very competent help,
our effort this fall would have had to be substantially less
and many fewer birds would have been banded. Laura was a banding
intern at Whitefish Point Observatory last fall and assisted with our long-term
study of the effects of acid mine drainage on the breeding
biology of the Louisiana Waterthrush this spring and summer.
Laura also helped with the creation and maintenance of this website while
she was here. Thanks, Laura!

Overcast and mild early AM; mild, overcast, increasingly
windy late AM Six Rusty Blackbirds caught--this
species is attracted at this time of year to the abundant white fruits
of red-panicled dogwood (Cornus racemosa) which grows in thick stands in
the vicinity of many of our net lanes
