PICTURE OF THE WEEK:


February 13, 2005:  Fresh snow over the past week, combined with strong winds,
resulted in drifts up to one metre deep in places.  However, this didn't deter the local
Northern Shrike (actually present in this photo as a small white dot high in a tree in
front of the forest) from singing at length.  (Photo by Marcel Gahbauer)

Bander-in-charge:  Marcel Gahbauer

Notes:  Days scheduled for banding this week were generally too cold or windy for the nets to be opened.  A single net was put up for a short while on Sunday morning while tending to other station duties, and a lone Black-capped Chickadee came in for a visit as a result.  It was one of the half dozen which had been banded a week ago.  For over an hour, a Northern Shrike sang almost without pause from a treetop near the banding cabin.  Also of note, for the second consecutive week there was a single Pine Grosbeak in the woodlot just south of the feeders.  The mystery rodent mentioned last week is a mystery no more - upon entering the cabin Sunday morning, I saw a Red Squirrel scurrying up a beam and disappearing through a small hole in the roof.  It has continued its chewing rampage inside, and now that we know its point of entry, will have to try to block it to prevent further damage.
