Parental investment of female Tengmalm?s Owls Aegolius funereus: correlation with varying food abundance and reproductive success
Original language description
The effects of food abundance, reproductive success and age of nestlings on parental care in female Tengmalm?s Owls were tested in this study. The behaviour of female owls was monitored by a camera system from hatching to fledging at 12 nests in 2004 and2006 in the Ore Mountains, Czech Republic. Food abundance and reproductive success (the latter measured at the end of female?s attendance of the brood) were higher in 2004 than in 2006. Females remained for a significantly longer time with their nestlings at the nests in 2004 (24.8 +- 2.4 days) than in 2006 (22.2 +- 0.9 days). During the attendance period, they were leaving the nest for several short trips each night; the duration of these trips, the total time spent outside the nest per night, and thenumber of trips per night did not differ between years.
