Shorebird avoidance of nearshore feeding and roosting areas at night correlates with presence of a nocturnal avian predator
We here report two anecdotes about avian interactions relevant to the interpretation of differences in shorebird habitat use between day and night. Several studies have reported that shorebirds avoid feeding and roosting along nearshore areas at night yet commonly use these sites during daytime. Thi...

We here report two anecdotes about avian interactions relevant to the interpretation of differences in shorebird habitat use between day and night. Several studies have reported that shorebirds avoid feeding and roosting along nearshore areas at night yet commonly use these sites during daytime. This suggests that nighttime avoidance of nearshore places is a response to increased danger of predation. When mist-netting during autumn 2005 on nearshore intertidal habitats along South Spit, Egegik Bay (Alaska Peninsula), Alaska, we discovered that shorebirds that occurred there in large numbers during daytime low tides and roosted there during daytime high tides (especially Dunlin Calidris alpina, Rock Sandpipers Calidris ptilocnemis, Black-bellied Plover Pluvialis squatarola, and Surfbirds Aphriza virgata), were absent at night.
