Record #188683:

Flexibility in the bimodal foraging strategy of a High Arctic alcoid, the little auk Alle alle / Jorg Welcker, and 5 others.

Title: Flexibility in the bimodal foraging strategy of a High Arctic alcoid, the little auk Alle alle / Jorg Welcker, and 5 others.
Author(s): Welcker, Jorg.
Date: 2009.
In: Journal of Avian Biology. (2009.), Vol. 40(4) (2009)
Abstract: Examines dual foraging trip pattern of little auks (Alle alle) at five colonies with contrasting oceanographic conditions. Colonies studied are adjacent to Greenland and Barents Sea in Arctic zone of Atlantic. In spite of wide variations in local conditions, little auks at all colonies show same general pattern of alternating single long trip with several consecutive short trips. However, foraging pattern is flexible and can be adjusted at three levels: length of long trips; frequency of short trips; and total time spent foraging. Birds facing unfavourable conditions increase duration of long trips and reduce number of short trips.
