Abstract
Nest defense and offspring protection were compared between male and female snowy owls N. scandiaca. In the 25 pairs observed the males were more aggressive than the females and often attacked the human intruder, while the females mostly used distraction display. The male is the most important defender of nest and offspring.This publication has 5 references indexed in Scilit:
