<p>Data from the experimental manipulation of food availability during early development and at recruitment for a long-lived seabird, the black-legged kittiwake Rissa tridactyla, breeding on Middleton Island, Alaska. Birds were born and raised in nests with supplemented food (“Fed”) or unsupplemented control nests (“Unfed”), and later recruited into either Fed or Unfed nests.</p>
