Human-produced noise, from transport, urbanization and industry, is widespread. Studies of
noise pollution show a wide range of effects on birds, such as alterations in communication …

There is considerable interest of evolutionary ecologists in the proximate mechanisms that
constrain life‐history variation. It is increasingly recognized that oxidative stress may be a …

In some areas of the world, climate-controlled poultry houses are not possible; thus, likely
resulting in lower production measurements and poorer quality poultry products due to lipid …

Background The amount of resources provided by the mother before birth has important and
long-lasting effects on offspring fitness. Despite this, there is a large amount of variation in …

The amount of food resources available to upper‐level consumers can show marked
variations in time and space, potentially resulting in food limitation. The availability of food …

Avian eggs exhibit a large variability in coloration and patterns, which are produced by blue-
green biliverdin and red-brown protoporphyrin pigments. Several hypotheses have been …

Avian eggshell color seems to fulfill multiple functions, some of them being structural and
others signaling. In this study, we tested whether or not eggshell coloration may play a role …

Daylight is an important factor necessary for the proper embryonic development of birds,
which raises the question, what happens when birds nest in relatively dim sites? The study …

Urbanization can cause innumerable abiotic and biotic changes that have the potential to
influence the ecology, behavior, and physiology of native resident organisms. Relative to …

Environmental challenges, such as fluctuations in food availability, could influence
reproductive investment. If resource availability is poor, individuals need to decide in which …
