Abstract:

A study was conducted on the Colville River delta, Alaska, during the summers of 1987 and 1988 to determine abundance, habitat use, and behavior of post-breeding shorebirds occurring in the littoral zone of the delta. The dunlin (Calidris alpina) was the most common species observed. Shorelines received the most use by shorebirds, particularly by dunlins and sanderlings (C. alba). The remaining 16 species, of which the semipalmated sandpiper (C. pusilla) was the most common, were most abundant in saltmarshes. Foraging dominated the activity of all shorebirds in occurring in all habitats of the delta. Shorebird abundance was correlated with prey abundance in shoreline and saltmarsh habitats.
