Abstract

Shorebirds were mist-netted at 500-ha of moist soil units ( Site A) and at a 400- ha riverine overflow basin (Site B) near the central Texas Coast from 1996-2001. A total of 3,745 shorebirds of 24 species were captured at the Site A at a rate of 76 birds per trip. A total of 1,543 shorebirds from 18 species were captured at the Site B at a rate of 106 birds per trip. Least Sandpiper (Calidris minutilla), Semipalmated Sandpiper (Calidris pusilla), Western Sandpiper (Calidris mauri), Dunlin (Calidris alpina), and Stilt Sandpiper (Calidris himantopus) were the most abundant species banded at Site A and were recaptured at the rate of 2.6%, 0.8%, 0.5%, 3.3%, and 0.8%, respectively. Least Sandpiper, Semipalmated Sandpiper, Western Sandpiper and Stilt Sandpiper were captured most frequently at Site B, and only two individuals were recaptured during years following banding. Banded birds were captured in Nebraska (Least Sandpiper), Ecuador (Semipalmated Sandpiper), and Alaska, British Columbia and Washington State (Western Sandpipers). More shorebirds were banded at Site A during spring and late summer/early fall at Site B.
