How the origin of novel behaviors can shape the evolutionary trajectory of organisms in
response to environmental change remains poorly understood. Birds, especially those with …

Nest construction behaviour is widespread among bird species. Causes for the occurrence
and great variation in nest characteristics between and within populations are still poorly …

Bird nests can be complex bio-engineered structures constructed from a range of materials
to provide a site for incubation, and in many species chick rearing. Reports of the materials …

Observational studies in the wild suggest that birds select material to build their nests based
on functional aspects of material that promote reproductive success. How birds select …

Studying nest construction provides insight into the functional and ecological aspects of this
key behaviour of avian reproductive biology. Studies have shown that passerines construct …

In many species of birds, the male feeds his partner during courtship. It is hypothesised that
courtship-feeding may nutritionally benefit females, strengthen pair-bonds, and/or signal …

The underlying mechanisms connecting correlated behaviors in wild populations remain
largely unknown. Food-caching behavior is a prime example of an adaptive, compulsive-like …

One of the most critical functions of nests in parids is thermal insulation, particularly during
egg incubation by females and during the first week of the hatchlings' life when they are …

Nest microclimate can be influenced by subtle differences in nest location such as
topography and aspect, and can differ among nests located relatively close to each other …

Many organisms engage in metabolic tradeoffs to manage costs associated with
reproductive output which often leads to these costs carrying over into the future …
