PICTORIAL HIGHLIGHTS, WEEK
10/24/00-10/29/00
-
10/28--First fall capture this
year for Henslow's Sparrow
and only the tenth bird of this species ever banded at Powdermill.
The bird, pictured below, was a hatching-year (HY) that had had an incomplete
molt of its primaries (having replaced 4-9 and the associated primary coverts)
and secondaries (having replaced 2-9). It was caught in the same
shelf of the same net that caught the Nelson's
Sharp-tailed Sparrow earlier this fall.
-
Banded a very late Wilson's
Warbler (imm. male, pictured below), fully
ten days later than our previous latest capture of this species
-
Banded an extremely late Chestnut-sided
Warbler (imm. male, pictured below) on 10/27,
two weeks later than our previous record of 10/12 in 1992--it had maximum
fat deposits and weighed 13.3 grams, making it one of only five records
out of 2,020 for this species in our database exceeding 13 g. Our
heaviest CSWA ever had a body mass of 15.2 g!
-
10/24--Banded our first owl of
the season, a gray phase
Eastern Screech Owl,
in a net opened before first light
-
Like the closeup photo showing the cryptic
dorsal plumage of a Common Snipe
banded last week (see Pictorial
Highlights), the photo below shows details of the beautiful vermiculated
wing and back plumage of this owl. The notched pattern on the outer
primary coverts (lower right of picture) enabled us to identify this as
an immature, or hatching year (HY), screech owl
-
Five Winter
Wrens banded 10/24 brings seasonal total to
42, tying our third highest fall total ever. With 2-3 weeks remaining
in the migration period of this species, we may yet exceed the current
record of 47 banded in the fall of 1997
