Background Chicks of precocial birds hatch well-developed and can search actively for food
but their homeothermy develops gradually during growth. This makes them dependent on …

Background Growth trajectories should be adapted to selective factors of each species'
environment. However, major sha** forces of growth and development are unclear …

Incubation length and hatching asynchrony are integral elements of the evolved
reproductive strategies of birds. We examined intra-and interpopulation variation in both …

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

The strategies by which animals allocate reproductive effort across their lifetimes vary, and
the causes of variation in those strategies are actively debated. In birds, most research has …

Phylogenetic study of the honeyeater family shows that the four insular species of the genus
Gymnomyza are polyphyletic, with the largest, the Crow Honeyeater G. aubryana, being a …

Understanding of avian incubation is primarily gained from species nesting during spring
and summer, under conditions markedly different from those prevailing in late winter. Using …
