Nocturnal migrating passerines have been proven (using radar and also faecal
pellet examination) to fall victim to 'on the wing' predation by the greater
noctule bat, in Spain. Apart from that, I understand such 'conflicts' are
considered rare.

But that's the other way round. The question was about birds catching
bats.
