PICTURE OF THE WEEK:


February 14, 2005:  This Blue Jay caught today was the tenth one banded since last
October.  This individual was recognizable as an after-second-year bird by the barring
on the bright blue alula feathers, visible in this photo  (Photo by Marcel Gahbauer)

Banding assistants:  Jean Brunet, Gay Gruner, Barbara Macduff, Betsy McFarlane

Notes:  It was largely another cold week, and again we were able to go out only once, on Monday morning.  Even then, it was too cold to open the nets right away, so we stayed inside and warmed up around the fireplace for a while before getting started.  During the brief period that we ended up having the nets open, we caught 10 birds, mostly Black-capped Chickadees.  Among the birds banded were also a Blue Jay, a Downy Woodpecker, and an American Tree Sparrow.  One of the chickadees had not been observed since last October, qualifying it as a return, rather than a repeat.  The local Northern Shrike was observed again, though it was silent this time.  The highlight of the day was a flock of 23 Bohemian Waxwings flying over the nets, our 137th species for MBO.
