Notes:
An unusually cold, windy, and snowy second week of March kept us from
banding. However, most of the regular species were seen during trips
to fill the feeders. Of interest, one of the American Tree Sparrows
was observed perching on the nyjer seed feeder, rather than just foraging
on the snow below as usual. We also learned this week from a
reliable observer that the local Great Gray Owl has in fact been seen as
far back as the end of January, sometimes even perched on top of our net
poles, or out in the open on the martin condominium!
