Tits recognize the potential dangers of predators and harmless birds in feeder experiments

Popis výsledku v původním jazyce

Accurate recognition of a predator is the necessary precondition for adequate antipredatory behaviour. We used feeder experiments to examine whether birds adopt the appropriate antipredatory response according to the level of threat posed by predators. The results support the idea that the tits made a decision on the threat level. The tits distinguished among equally sized obligatory predators (sparrowhawk, kestrel), an occasional predator (jay) and a harmless bird of similar size (pigeon) and a smallerharmless bird (thrush). The presence of both birds of prey was associated with a considerable reduction in the number of feeder visits when compared with the harmless birds. The number of visits to the feeder that had a dummy jay positioned on it did not significantly differ for harmless birds or for predators. Different sizes of harmless birds did not influence the tits? behaviour. The increasing risk lowered not only the number of visits to the feeder but also the success of the visit
