ABSTRACT
The forest surrounding our house is mainly composed of spruce, pine, poplar, and aspen trees. Two Evening Grosbeaks have taken up strategic positions on a tall pine near the feeder and are swooping down on it in measured flights. Their flights are cut by calls of complaint from several Blue Jays evenly spread through the surrounding trees. In their approaches, they deftly balance the swoops of air and space between them and the feeder, the wind that has picked up, and the way the feeder sways-loosely hung to avoid the cats who watch these events in wide-eyed frustration.
