Activity patterns of male Tengmalm?s owls, Aegolius funereus under varying food conditions

Popis výsledku v původním jazyce

This study investigated whether the males of the Tengmalm?s owl change their activity patterns, evaluated based on delivering prey to nestlings in respect of different food supply. During two breeding seasons 12 owl nests were continuously monitored by acamera system to obtain data on the time of male prey delivery and identification of prey items brought to nestlings. Even though the abundance of food supply differed in both years, there was no difference in the number of prey items delivered by malesto their nests. Nevertheless, the species composition of food supply as well as the species composition of prey delivered by males to the nests differed between 2004 and 2006. Yet male activity patterns were the same in both years; they showed a monophasic cycle with one peak at the beginning of the night, around 22:00 and 23:00.
