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.
