PICTURE OF
THE WEEK: |

So far it is still very much the winter of the House Finch at
MBO - they account for
over one third of the birds we have banded, and are routinely
the most abundant
species at the feeders.

Notes:
For a couple of days this week it was very cold; at other times it
remained unseasonably mild but again wet. At least we were able to
squeeze in one attempt at banding this week, but gusty winds severely
hampered the effectiveness of the nets, with just 3 new birds banded,
and another 4 repeats. Nonetheless, it was good to get back out
and into action. Another two species were added to the winter
2006/07 list, with a Great Black-backed Gull spotted flying overhead on
Saturday, and two Snow Geese in the skies the following day. The
big story though remains the phenomenal number of Canada Geese still in
the area - 935 counted on Saturday, and 1600 on Sunday! Mallards
are also still present in large numbers, reflecting the late start to
winter this year.
