| Methods: | Standard breeding bird censuses with 100 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. Observer distinguished between birds within 50 m of the center point, birds from 50-100 m, and those beyond 100 m. Counts carried out from late May through August over a three-year period. Placement of circles within vegetated salt marsh habitat. NOTES AND COMMENTS: Temperature inconsistently recorded |
