Jannik Hansen, Malin Ek, Tomas Roslin, Jérôme Moreau, Maria Teixeira, Olivier Gilg, Niels Martin Schmidt. (2015). First Observation of a Four-egg Clutch of Long-tailed Jaeger (Stercorarius longicaudus) (Vol. 127).
Abstract: Long-tailed Jaegers (Stercorarius longicaudus) normally lay one or two eggs (rarely three), with a maximum of two eggs set by the existence of only two brood patches. Here, however, we present the first documentation of a clutch of four eggs in a Long-tailed Jaeger nest found at Zackenberg in northeastern Greenland.
