The study of intraspecific geographical variation of non-passerine vocalizations remains under-studied, especially in African species. We explored spatial patterns in call variation of the Crested Francolin Dendroperdix sephaena across its wide [...]

Taxonomists now usually recognize 10 extant species of oystercatcher Haematopus, plus the extinct Canary Islands Oystercatcher Haematopus meadewaldoi. Molecular data, however, have recently been used to propose meadewaldoi as either a morph or a[...]

African Penguins Spheniscus demersus are endangered and declining seabirds which make extensive use of vocal signals for intra-specific vocal communication. Accordingly, passive acoustic monitoring tools could be developed as robust population m[...]

Whereas most migratory animals, such as many birds of prey, return to the same breeding area each summer, nomadic breeders search over large distances to locate breeding areas that vary greatly in location from year to year. Nomadic breeders are[...]

The materials that birds use to build their nests have a profound effect on nest quality and consequently on the builder’s reproductive success. Given that the common method to quantify nest materials by dismantling nests takes time and limits s[...]

The ecological reasons for variation in avian migration, with some populations migrating across thousands of kilometres between breeding and non-breeding areas with one or few refuelling stops, in contrast to others that stop more often, remain [...]

Social cues can improve estimates of foraging site predation risk beyond that of individual assessment alone, as they provide current, accurate information, and the importance of these cues may be greater in higher risk environments. We assessed[...]

Mountain areas still feature remnants of traditional land use and consequently constitute a large proportion of the remaining species-rich habitats in Central Europe. However, their biodiversity is increasingly threatened by changes in climate a[...]

During autumn migration, bird-eating raptors are thought to rely on flocks of migrant songbirds (Passeriformes) as a critical resource to fuel the energetic demands of long-distance migration. However, this hypothesis has been challenging to inv[...]

In snowy winters, the survival of Tawny Owls Strix aluco of the grey colour morph is suggested to be better than that of the brown (or red) morph, partly due to their paler plumage, which is presumed to provide better camouflage against predatio[...]

The plumage of birds plays an essential role in thermal insulation and influences the heat tolerance of birds. These plumage functions are mainly determined by the number and the density of feathers, but it is unclear how feather density respond[...]

Ground-nesting shorebirds rely on egg crypsis as one of their main anti-predator defence strategies. Avian embryos vocalize late in incubation and communicate with parents through the eggshell but calls may compromise crypsis. Conceivably, embry[...]
