PICTURE OF THE WEEK:


The Common Redpolls have begun to increase in numbers.  This after-hatch-year male was remarkably tame, continuing to feed from the nyjer tube even when there was human activity only a few metres away.  (Photo by Marcel Gahbauer)

Bander-in-charge:  Marcel Gahbauer
Assistants:  Shawn Craik

Notes:  No banding this week, due to weather in combination with busy schedules in advance of the holidays.  The highlights of the week were our first Red-breasted Nuthatch sighting of the winter, and increasing numbers of Common Redpolls, with as many as 6 by Thursday.  On Friday, 41 cm of snow fell, the highest single day accumulation in over 30 years.  It will be interesting to see whether this results in more birds concentrating at the feeders.
