The yard contained a large maple tree {Acer sp.), several smaller trees, and a dense row of cedar trees {Thuja sp.) growing along a chain link fence. We accustomed a group of birds to the study area by supplying them with black sun- flower seeds two weeks prior to commencement of the study. Three feeding stations were set up perpendicular to and m (Station 1), m (Station 2), and m (Station 3) respectively, from the row of cedar trees (Figure 1). Each feeding station contained two feed- ers that were 20 cm apart. The three feeders closest to the house ( m away) were designated B feed- ers, and the other three feeders were designated A feeders; A feeders were closest to the large maple tree (Figure 1). The observer was positioned near the house, m from the B feeders (Figure 1). Each.
