Bander-in-charge:  Marcel Gahbauer
Banding assistants:  Shawn Craik

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!
