Territorial intrusions and copulation behaviour in the great skua, Catharacta skua
Article Abstract:
There is evidence that monogamous female great skuas, Catharacta skua, trade extra-pair copulations for food. It seems that females intrude on to territories to encourage males to give away some food, especially as all extra-pair copulations observed by researchers were preceded by courtship feeding. The females may also be seeking to identify potential partners for future breeding seasons. Males could be stimulated to continue to provide females with food through other behaviours, including the 'squeaking ceremony.'
