Black-capped Chickadees banded this week, an adult that stopped
pecking at
fingers just long enough to allow this picture to be taken.

Notes:
Wednesday morning we went out for banding but it was unexpectedly cold
and we were limited to observations; Sunday was expected to be a census-only
day, but it ended up nice enough to allow for a bit of banding before the
snow began to fall. The uncertainties of winter...
The
bird of the week was a Rusty Blackbird discovered on the back loop of the
census trail on Sunday morning, seeking out a melted trickle of water amidst
the dusting of snow on the ground. It was later seen near the feeders,
so it may stay around for a while. Also notable was an American Robin,
and a surprisingly large (for this date) flock of 118 Canada Geese.
Among
the birds banded, Black-capped Chickadees were again the most
numerous. It may be that the large migration observed this fall is
still not quite over. We also had a return of a Black-capped Chickadee
last seen February 14 this year. Last week we recaptured two other
chickadees banded that day and not seen since - it would be interesting to
know where this little flock went in the interim, but we can only guess.
