Pomarine Jaeger
Stercorarius pomarinus
  • Comments:  Individual variations and two color morphs make it difficult to differentiate among the three jaegers. Pomarine Jaegers are larger, have a heavier, barrel-chested appearance and broader and longer wings than other jaegers. Although usually lost soon after leaving their arctic breeding grounds, the two central tail feathers are broad, blunt, have a halftwist and extend beyond the rest of the tail. On breeding grounds their main food is lemmings.
  • Pomarine Jaegers occur in small numbers or are found only in localized sites within the Great Plains.
