| Title: | Seasonal changes in food habits of gyrfalcons in NE-Iceland / Ólafur Karl Nielsen, Tom J. Cade. |
| Author(s): | Nielsen, Ólafur Karl. Cade, Tom J. |
| Date: | 1990. |
| In: | Ornis Scandinavica. (1990.), Vol. 21(3) (1990) |
| Abstract: | Food habits of three sub-populations of Falco rusticolus were studied in coastal, lakeland and heathland habitats of north-eastern Iceland by analysis of 2316 pellets collected from February 1984 to July 1985. Rock ptarmigan [Lagopus mutus] was main prey and most important during early phase of breeding season (April-June) and between August and December. Coastal gyrfalcons had most variable diet. Switching to alternate prey involved in most cases change of hunting habitat. |
