There are only six known occurrences of this species in the Pribilofs, all in the spring during late May or early June except for a single fall record in late September. However, there is no reason to believe this species isn’t possible at any time during spring, summer, or fall with recent records in Alaska during late summer as well. This species was once lumped with the Marbled Murrelet (Brachyramphus marmoratus) and was only split in the early 2000s. The records of Marbled Murrelet preceding this split are still believed to pertain to that species.
