Mimicry has long been a focus of research, but little is known about how and why many
species of bird incorporate imitations of heterospecific sounds into their vocal displays …

The efficacy of nest-site choice ultimately determines the breeding success of birds.
Comparisons of the reproductive strategies of various bird species which inhabit the same …

Closely related birds that occur sympatrically will inevitably differ in the acquisition of food
resources, nest site selection, and breeding times. The successful coexistence of birds that …

Niche theory predicts that ecologically similar sympatric species should show differentiation
in at least one of the main niche dimensions (time, space, and/or food). Here, we combined …

Breeding in alpine environments poses significant challenges to birds, requiring specific
adaptations for survival. The Sclater's monal (Lophophorus sclateri), a regionally threatened …

Background Floods and other extreme events have disastrous effects on wetland breeding
birds. However, such events and their consequences are difficult to study due to their rarity …

The remarkable diversity of ecological niches that birds have evolved to inhabit have
resulted in their status as model organisms to study how the same morphological features …

Understanding nest site selection is critical to developing effective conservation
management actions. The Superb Lyrebird (Menura novaehollandiae) is one of many …

Landscape heterogeneity, from both natural and anthropogenic causes, fundamentally
influence the distribution of species. Conservation management requires an understanding …
