PICTURE OF
THE WEEK: |

Last week we wrote that winter has arrived at last; the photo
above shows that it quickly
disappeared again! Not only is the landscape entirely
brown and green, but the male
American Goldfinches are already starting to acquire their black
caps for spring!

Notes:
We actually managed to get our two
days of banding in this week thanks to the continued unseasonably warm
weather this winter has provided thus far. Gusting winds and the lack of
snow, however, made our total catch somewhat modest. In fact on Sunday,
there were six times as many volunteers on site than birds banded!
On the other hand, under calmer conditions on Wednesday, the birds
outnumbered people by a 12:1 ratio. We didn't mind the Sunday
outcome though, because we were outside on such a beautiful day, and
took advantage of the quiet nets to walk around the site and spot our
local young male Cooper's Hawk hanging out by the D nets. The birds at
the feeders were unimpressed when he buzzed them later in the morning.
American Goldfinches (finally arriving in good numbers) and Black-capped
Chickadees (surprisingly many 'new' birds) were this week's top banded
species, with six each.
