Reproduction in a population of the hooded crow corvus cornix

Reproduction in a population of the hooded crow corvus cornix

Holarctic Ecology 3(1): 26-35

Nest density was stable during the 8 yr study period [in south Sweden]. The mean clutch size was 4.3, and the production of fledglings was 2.0/pair. Incubation started, on average, when there were still 2 eggs to be laid and lasted for 18 days. Few eggs were lost but 23% of all broods of nestlings were lost to predators. Single nestlings in a brood were not lost to predators but often starved to death; this applied to 25% of all nestlings. A large proportion of the nestlings were probably infected by Syngamus tracheae, and some of these succumbed during the 1st wk after fledging. A comparison with other studies of crow populations shows that the major causes of breeding failure are different in different populations. The causes of variation in breeding success between populations are discussed, especially considering the role of nonbreeding crows.
