Matning av ungar hos svarthakedopping Podiceps auritus

Abstract

This article describes a study of the differences between sexes of the Slavonian Grebe Podiceps auritus when feeding their young. Seven pairs were studied at a lake, size 1.6 ha, in southern Sweden. Each young was fed 16.5±1.71 times per hour, and the feeding was split equally between the male and the female parent. Duration and number of diving series of the parents were the same for male and female. With increasing age of the young, the male and the female grebe increased their feeding rate.
