| Description
| - 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 of Myotis 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 the emergence and they often concentrate near the roost during their early practice flights, making them more vulnerable to owl predation then adults.

- Sovy selektivně loví menší a mladší hlodavce, ovšem neexistují důkazy o selektivní predaci sov na netopýrech. V této práci jsme se zabývali predací netopýra velkého (Myotis myotis) sovou pálenou (Tyto alba). Soubor lebek Myotis myotis z vývržků Tyto alba byl srovnán s kontrolním souborem lebek z muzejních sbírek a bylo zjištěno, že lebky pocházející ze sovích vývržků jsou menší. Rozdíly byly nejvíce zřetelné u délek zubních řad v dolní a horní čelisti a v šířkách rostra mezi zuby v horní čelisti. Naše výsledky naznačují, že sovy preferují tohoroční vzletná mláďata netopýrů, která jsou téměř stejně velká jako dospělci, ale nemají dostatek zkušeností a jsou tedy pro sovy snadnější kořistí. Tato mláďata jsou méně obratná v letu, jsou tudíž nápadná během výletu z kolonie a navíc se po výletu často soustřeďují v blízkosti úkrytu a jsou tedy snáze ulovitelná. (cs)
