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.
