Black-crowned Night-Heron

Nycticorax nycticorax

There is a single early spring (April) and two summer (July and August) records for this species in the Pribilofs. The early spring arrival fits a pattern similar to those seen in the western Aleutians, while the summer records are likely to be individuals undergoing post-breeding dispersal like many other herons and egrets do.
