Résumé : | Hunting by Aegolius funereus (L.) was studied by direct observation, and various phases of the prey capture were photographed. The owls hunted in forest land and frequented dense parts of the forest where they flew skilfully. They searched for prey from low perches, mean height 1.7 m, and waited a short time at each perch, mean 1A min. Mean distance between perches was ca. 17 m. Strikes occurred from close range, ca. 4.5 m. The owl's eyes were closed for protection just before impact. At impact the talons of both feet combined covered an area approximately 4 by 6Q cm. The prey was usually killed by bites in the head or back of the neck. Due to its choice of low perches and strike from close range, the owl can make good use of auditory clues.
