: Non-breeding. mid Jun-late Aug. Not confirmed from the mainland.
Migration: late May-early Jun and early Sep-mid Nov, with likely to early/mid Dec or even later were observers present to record them. from Schoodic Point Aug 28, 2019. No other confirmed records from mainland observation points or from Frenchman or Blue Hill Bays.
Miscellany: The status of jaegers in our waters is complicated by the fact that other than fully tailed adults, the separation of the three species can be difficult. The Bar Harbor whale watch vessels that visit locations offer the only realistic public chance to see Pomarines
Pomarine Jaegers are possibly unique among birds in that their successful breeding depends on a single resource, the Brown Lemming (or outside of North America, a close relative), and only once every three or four years when lemming numbers peak. If on return to their high arctic breeding areas, they find too few lemmings, they return quickly to the open oceans where they spend the rest of the year.
