Changes in demographic rates underpin changes in population size, and understanding demographic rates can greatly aid the design and development of strategies to maintain populations in the face of environmental changes. However, acquiring estim[...]

Songbird nests are an important life-history component with multiple functions, including the creation of a suitable microclimate for offspring development. Thus, functional nest characteristics may influence fitness correlates, such as nestling[...]

Populations of long-distance migrant birds are declining but it is unknown what role land cover change in non-breeding areas may be playing in this process. Using compositional analysis, we assessed habitat selection by one such migrant, the Woo[...]

Information about how bird species respond to increasing density conditions through either space-use sharing or increased territoriality, and how those changes affect fitness, is essential for effective conservation planning. We used a case stud[...]

Grounding of thousands of newly fledged petrels and shearwaters (family Procellariidae) in built-up areas due to artificial light is a global problem. Due to their anatomy these grounded birds find it difficult to take off from built-up areas an[...]

On islands, colonizing birds may evolve behavioural and morphological adaptations to the new environment, often resulting in changes in body size and reduction or even total loss of flight. These island populations have therefore been used to te[...]

Radiotelemetry is an essential method for studying the movements and survival of cryptic grassland bird fledglings. There is mixed evidence on the effects of wearing radio-transmitters for passerines, with negative consequences probably under-re[...]

The probability of Blue-footed Booby Sula nebouxii fledglings becoming reproductive adults is maximal when one parent is old and the other young, and minimal when both are old or young. No mechanism has been identified to explain this pattern, b[...]

Given the rarity of hybridization in seabirds, which presumably relates to their very high philopatry, the degree of breeding-site vagrancy should correspond with the incidence of mixed-species pairing, although not necessarily with the producti[...]
