Niche separation between the merlin (Falco columbarius) and the Eurasian hobby (Falco subbuteo) nested on pine bogs of Northern Belarus

Бесплатный доступ

Nest spacing, types of nests used and feeding habits were compared for the Merlin ( Falco columbarius ) and Eurasian hobby ( F. subbuteo ) on extended pine bogs of Northern Belarus. In 2008-2017, 60 nesting cases of Merlins and 20 nesting cases of Hobbies were analyzed. A total of 381 prey remains of the Merlin and 336 prey remains of the Hobby were sampled and identified for the dietary analysis. Overlap of ecological niches between the two species was relatively low showing effective resource partitioning in a result of evolutionary divergence. Thus, observed decrease in numbers of the Merlin in the last decades was not related with increasing numbers of the Eurasian hobby.
