Abstract: | On the basis of long-term studies on the ecology of pied flycatcher in Karelia, it has been shown that male nonparticipation
in nestling feeding is due to the course of postnuptial molt rather than to the mode of mating relationships, as it was considered
previously. This is confirmed by the results of selective capture of birds that have stopped to feed their brood. It is suggested
that reduction of parental care is associated with changes in the hormonal balance of molting birds. |
