Individual variation in behavior and physiology is a widespread and ecologically functional
phenomenon in nature in virtually all vertebrate species. Due to domestication of laboratory …

Over the past decade, birds have proven to be excellent models to study hormone-mediated
maternal effects in an evolutionary framework. Almost all these studies focus on the function …

Physiological Adaptations for Breeding in Birds is the most current and comprehensive
account of research on avian reproduction. It develops two unique themes: the consideration …

record and evolution of avian egg nesting and incubation/DC Deeming--Nest construction …

The signalling function of melanin‐based colouration is debated. Sexual selection theory
states that ornaments should be costly to produce, maintain, wear or display to signal quality …

Melanins are the ubiquitous pigments distributed in nature. They are one of the main
pigments responsible for colors in living cells. Birds are among the most diverse animals …

In commercial egg production, chicks are exposed to a potentially stressful procedure during
their first day of life. Here, we investigated how this procedure affects the chickens in a short …

Publisher Summary This chapter discusses the physiology, ecology, and behavior of
hormones in avian eggs. The main source of hormones found in avian eggs is the maturing …

The survival probability of birds during the juvenile period, between the end of parental care
and adulthood, is highly variable and has a major effect on population dynamics and …

The steroid hormone testosterone (T) plays a central role in the regulation of breeding in
males, because many physiological, morphological and behavioural traits related to …
