Our understanding of the full life cycle of most migratory birds remains limited. Estimates of survival rates, particularly for first-year birds are notably lacking. This knowledge gap results in imprecise parameters in population models and lim[...]

Increasing aridity during glacial periods produced the retraction of forests and the expansion of arid and semi-arid environments in Africa, with consequences for birds. Cattle egret Bubulcus ibis is a dispersive species that prefers semi-arid e[...]

The function of female birds' extra-pair (EP) behavior has remained an unresolved question in ornithology and behavioral ecology for. 30 yr. The genetic compatibility hypothesis (GCH) proposes that females benefit by acquiring biological sires t[...]

Birds may change their diet and foraging habitat during or after migration. Dunlins Calidris alpina alpina breed in the tundra of northern Europe and Russia where they feed exclusively on terrestrial prey. However, up to 80% of the flyway popula[...]

Song is a notable sexual signal of birds, and serves as an honest indicator of male quality. Condition dependence of birdsong has been well examined from the viewpoint of the developmental stress hypothesis, which posits that complex songs assur[...]

Avian hosts of brood parasites can evolve anti-parasitic defenses to recognize and reject foreign eggs from their nests. Theory predicts that higher inter-clutch and lower intra-clutch variation in egg appearance facilitates hosts to detect para[...]

The loss and degradation of natural habitats in coastal areas worldwide has adversely affected many waterbird species, changing their breeding distribution and reducing their productivity. Anthropogenic habitats such as saltpans can provide alte[...]

Nest predation is a widespread demographic and evolutionary force in avian reproduction, but few studies have considered the circumstances under which birds might invest in the construction of safe nests. We examined this question using a stocha[...]

European populations of the white-tailed eagle Haliaeetus albicilla suffered a drastic decline during the 20th century. In many countries, only a few dozen breeding pairs survived or the species disappeared completely. By today, the populations [...]
