Methods:Standard breeding bird censuses with 50 m radius counting circles. Observing periods divided into 0-3 min, 3-5 min, and 5-10 minutes for comparison with other censuses. For 3-5 min period, only additional birds not recorded in the 0-3 period are recorded. For 5-10 min period, only additional birds not recorded in the 0-5 min period are recorded. Birds recorded either visually or by sound. Counting circle boundaries set a minimum of 200 m from each other. Counts carried out from late May through early July with most counts in June. Placement of circles encompassed a variety of habitats.
