Cliff Swallow

Petrochelidon pyrrhonota

A predominantly spring arrival in the Pribilofs, this species is less-than-annual at that time but still seen with some regularity. While records are scattered across much of the spring period from mid-May to mid-June, the majority of records have occurred from May 20th-June 1st and from June 15th-20th. The handful of summer records are generally “late spring” arrivals, with two records of likely southbound birds in the late summer period.
