- Abstract
During 2009 and 2010 in the city of Pécs (Hungary) 59 active blackbird (Turdus merula) as well as 59 artificial nests were observed. Among the real nests 26 (44%) were successful, 14 (24%) were predated, and 19 (32%) were abandoned by the parent birds. Among the artificial nests 34 (57%) remained intact, but 25 (42%) were predated. Regarding the failure of real nests, if we consider both predation and abandonment during the incubation period, the daily survival rates of real nests (n = 59) DSR (0.952) were significantly lower than the DSR of artificial nests (0.977). If we consider only predation rates (n = 41), the daily survival rates of the two nest types did not differ significantly (real nests 0.976, artificial nest 0.978). Consequently, the daily survival rates of artificial bush nests used by us reflect precisely the predation pressure on real blackbird nests.
