It was more a case of the female trying to keep contact with the male especially during breaks in the incubation, than vice versa. None of the mate guarding predictions was thus supported by our data. We suggest that the combination of elaborate copulation ceremony of the nuthatch (which ...
Two hypotheses could explain observed male-biased gene flow between and among mitochondrial populations: male-biased dispersal and female hybrid sterility or inviability (Haldane, 1922; Illera et al., 2011). Our analyses lack the evidence to reject or support the potential role of female hybrid ...

brought smaller prey items to the nest than females. These findings are discussed in the light of morphological differences between male and female beak size. We conclude that sexual selection has favoured conspicuous male signalling in this system, and that natural selection should select for reduced...

Capercaillie behavior, both in the wild and in captivity, is poorly known due to this species’ secretive way of life. Female-male and female–female social organization and interactions are especially poorly documented. The research was conducted in Capercaillie Breeding Center in Wisła Forestry ...
