Observers: Sophie Cauchon, Shawn Craik, Gay Gruner, Andre Pelletier, Greg Rand

Notes:  Although we did not have the chance to do any banding this week, observations indicated considerable activity around the feeders.  Of particular interest were 2 Common Grackles (first observation of this species this winter) and at least 13 Northern Cardinals gorging themselves at the feeders.  However, Black-capped Chickadees and American Tree Sparrows remained most abundant around the feeder area.  Other highlights throughout week 20 included flocks of Cedar Waxwings and Canada Geese and at least 2 individuals of the 3 common woodpecker species: Downy, Hairy, and Pileated.  With southern winds forecasted for later this week, we anticipate the arrival of additional early migrants, including Red-winged Blackbirds, to MBO soon.
