The importance, extent, and mode of interspecific gene flow for the evolution of species has
long been debated. Characterization of genomic differentiation in a classic example of …

In most cooperative vertebrates, delayed natal dispersal is the mechanism that leads to the
formation of kin societies. Under this condition, the possibility that kin-based cooperative …

Climate change affects timing of reproduction in many bird species, but few studies have
investigated its influence on annual reproductive output. Here, we assess changes in the …

Avian brood parasites lay eggs in the nests of other birds, which raise the unrelated chicks
and typically suffer partial or complete loss of their own brood. However, carrion crows Corvus …

The Carrion Crow (Corvus corone) is almost invariably reported as a species breeding as
unassisted pairs, but a population of Carrion Crows (Corvus c. corone) from northern Spain …

Kin-based societies, where families represent the basic social unit, occur in a relatively
small number of vertebrate species. In the majority of avian kin societies, families form when …

Cooperatively breeding birds typically form cohesive and stable groups that live year‐round
in all purpose territories where competition for resources is likely to arise. Understanding …

Interactions between brood parasites and hosts can lead to coevolutionary arms races,
whereby hosts evolve defences such as ejection of alien eggs and nest defence, and parasites …

The effect of group size and the number of helpers on reproductive success is crucial to
understand the evolution and maintenance of cooperative breeding. In northern Spain, carrion …

The social behaviour of carrion crows varies between populations. In northern Spain
cooperatively breeding groups form through delayed natal dispersal and/or immigration of …
