Název v původním jazyce

Does the barn owl (Tyto alba) selectively predate individual great mouse-eared bats (Myotis myotis)?

Popis výsledku v původním jazyce

There is a good evidence that owls prefer to prey on smaller and younger rodents, but nothing is known about possible selective predation on bats. We studied predation on the mouse-eared bat (Myotis myotis) by the barn owl (Tyto alba). A set of skulls ofMyotis myotis from pellets of Tyto alba was compared with a control one (samples from museum collection) and it was found out that skulls from owl pellets were smaller. The differences were mainly in lengths of upper and lower toothrow and rostral breadths across upper teeth. Our results indicate that Tyto alba most probably prefer to prey on volant inexperienced yearlings which are easier to catch, whilst reaching almost adult size. Volant yearlings lack flying skills, they are conspicuous during theemergence and they often concentrate near the roost during their early practice flights, making them more vulnerable to owl predation then adults.
