Status: Accidental in spring. Rare casual fall migrant statewide.
Documentation: Specimen: UNSM ZM13093, 1 Sep 1952 Lancaster Co (Baumgarten and Rapp 1953).
Taxonomy: Two subspecies are recognized (Gill and Donsker 2017): longicaudus of northern Scandinavia and northern Russia, and pallescens of eastern Siberia, arctic North America, and Greenland. Nebraska birds are presumed pallescens.
Spring: There is one documented record, although the several reports from neighboring states, most in late May-Jun, suggest that Long-tailed seems to be the most likely of the jaegers to occur in spring.
9 Jun 2008 adult photographed Lake McConaughy, Keith Co (Brogie 2011).
Fall: There are ten documented records, several of which were discussed by Dinsmore (2009), who stated the species “may be a more common migrant in western Nebraska than previously thought”.
