Caught on camera !

A previous work by Ana Sanz-Aguilar (here) has showed that a small number of highly specialized gulls was responsible for the observed predation at a colony of an European Storm Petrel. Selective culling directed to these individuals improved petrel breeding sucess and survival, an indication that massive culling plans might well miss the target. Ten years after, Ana found some new kids in town ... and this time she took them on camera!
