To maximize the effectiveness of conservation interventions, it is crucial to have an understanding of how intraspecific variation determines the relative importance of potential limiting factors. For bird populations, limiting factors include n[...]

Climate may influence the distribution and abundance of a species through a number of demographic and ecological processes, but the proximate drivers of such responses are only recently being identified. The Ethiopian Bush-crow Zavattariornis st[...]

In some tropical birds, breeding seasonality is weak at the population level, even where there are predictable seasonal peaks in environmental conditions. It therefore remains unclear whether individuals are adapted to breeding at specific times[...]

Avian species have developed a range of markers for transmitting information, among them ornamented plumage, behavioural patterns and conspicuous bill structures. Members of the marine subfamily Fraterculinae have some of the most visibly notice[...]

Investigating the reproductive ecology of naturalized species provides insights into the role of the source population's characteristics vs. post-release adaptation that influence the success of introduction programmes. Introduced and naturalize[...]

Birds’ eggs often exhibit considerable variation in the presence and pattern of superficial pigmentation, or maculation. However, despite long appreciation of the nature of this variation both between and within species, there is still poor unde[...]

Nest attendance behaviour in birds is a function of the careful balance between the risk of nest predation and the needs of the parents and nestlings. This attendance must be carefully regulated, as increased parental activity at the nest increa[...]

Among the many unique flight behaviours of Common Swifts Apus apus, the most puzzling may be their ascents to high altitudes during both dusk and dawn. Twilight ascents have been hypothesized to be functionally related to information acquisition[...]

Habitat edges alter the diversity of avian communities and are often associated with higher rates of nest predation. However, most previous studies on habitat edges have been conducted along long linear corridors or at the transition between lar[...]

Populations from different parts of a species range may vary in their genetic structure, variation and dynamics. Geographically isolated populations or those located at the periphery of the range may differ from those located in the core of the [...]

Populations found at the edge of a species range often have decreased genetic diversity, which together with high gene flow may reduce the ability of a species to adapt to local environmental conditions. The Dead Sea Sparrow Passer moabiticus oc[...]

Understanding the characteristics of the international bird trade is critical for preventing the traffic of endangered species. Japan is the second largest importer of birds for the pet industry globally, yet little research has examined its rol[...]

Identifying factors influencing the demographics of threatened species is essential for conservation, but a lack of comprehensive demographic data often impedes the effective conservation of rare and mobile species. We monitored breeding of crit[...]

To use vocalizations properly for the estimation of owl population size, it is important to identify how environmental factors affect owl calling behaviour. Here, we analyse how intrinsic and extrinsic factors modify the vocal activity of Tawny [...]

In the majority of songbird species, males have repertoires of multiple song types used for mate attraction and territory defence. The wood-warblers (family Parulidae) are a diverse family of songbirds in which males of many migratory species us[...]

A recent broad comparative study suggested that factors during egg formation – in particular ‘flight efficiency’, which explained only 4% of the interspecific variation – are the main forces of selection on the evolution of egg shape in birds. A[...]
