Observers:  Sophie Cauchon, Shawn Craik, Barbara Frei, Marie-Anne Hudson, Andre Pelletier

Notes:  Frigid temperatures throughout this two-week period continued to postpone banding activities.  There were no major changes in species composition near the feeder area, as Black-capped Chickadees, Slate-coloured Juncos, American Tree Sparrows, and Mourning Doves were the usual suspects at and under the feeders.  However, observation highlights included the regular viewing of an adult Red-tailed Hawk and an extremely vocal group of 20-25 House Finches.  Also of note was the surprising absence of northern Cardinals - only a single male was observed throughout the two-week period.
