L. heuglini Heuglin's Gull

NOTE: This taxon is often considered a subspecies of L. fuscus Lesser Black-backed Gull. Paler breeders in the eastern part of the range of heuglini are often separated as L. heuglini taimyrensis, Taimyr Gull, but may be hybrids of heuglini and L. vegae.
L. h. taimyrensis An adult was photographed in fall 2010 in the nw. Hawaiian Is (Force), thought to be a first record for the Hawaiian Is. Pyle and Pyle (2009) note: "An .....individual photographed on Kure in March 1988 (HRBP 0812-0813) may be smithsonianus or "taimyrensis" (possibly a hybrid between Herring Gull and Lesser Black-backed Gull L. fuscus heuglini)."
