Avian nests are critical for successful reproduction in birds. Nest microclimate can affect egg
development, chick growth and fledgling success, suggesting that nest building behavior …

The evolution of nest site use and nest architecture in the non-avian ancestors of birds
remains poorly understood because nest structures do not preserve well as fossils …

Innovations in nest design are thought to be one potential factor in the evolutionary success
of passerine birds (order: Passeriformes), which colonized new ecological niches as they …

Avian nests are crucial to reproduction as they are the site for incubation of the clutch of
eggs and, in many cases, it is the location for the rearing of chicks hatched. Despite many …

Bird eggs can be spherical, ellipsoid, ovoid, or pear‐shaped (pyriform), the latter being the
most complex. There is however no unambiguous evolutionary/adaptive explanation for this …

The study of avian nesting biology in North America and Europe has a long history, resulting
in an expansive and information‐rich literature. In contrast, the tropics have been relatively …

Highlights•We examined correlated evolution between nest and egg characteristics in
birds.•The ancestral state of nests was semi-open with nest sites becoming more …

Global warming and intensifying extreme heat events may affect avian reproductive success
and costs, particularly in hot, arid environments. It is unclear how breeding birds alter their …

Diversity in the shapes of avian eggs has intrigued biologists for centuries, and recent
studies at a range of taxonomic scales suggest that egg shape can be a powerful lens …

Avian nests are fundamental structures in avian reproduction and face strong selective
forces. Climatic conditions are likely to have shaped the evolution of specific nest traits, but …
