With a bit more snow and colder temperatures at last, the
American Goldfinches are
becoming a more regular sight on the nyjer seed feeders.

Notes:
Weather has not permitted for any
banding during these two weeks, and observed bird activity was
relatively quiet aside from a lock of 20+ House Finches regularly
observed around the feeder area. However, the lack of snow in week 11 allowed for
walking a portion of the census trail, with the highlight being a group
of 3 American Robins along the path behind the cabin. Following
the snowstorm on January 15, bird activity around the feeders appeared
to pick up. In particular, there was a marked increase in the
number of juncos attending the feeder area. The higher level of
bird activity may have attracted the Northern Shrike that was seen
perched near the A nets just west of the feeders.
