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

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.
