The eggshell quality declined with extending of chicken laying cycles. Eggshell quality is a
crucial feature that not only affects consumer preference, but also influences producers' …

Evading detection by predators is crucial for survival. Camouflage is therefore a widespread
adaptation, but despite substantial research effort our understanding of different camouflage …

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

Birds are unique in laying eggs with pigmented shells, but for most species (eg most
passerines, which lay white eggs speckled with reddish spots of protoporphyrin) the …

Predation is a major evolutionary force in animal ecology. Mechanisms by which prey
coloration provides camouflage has been widely studied. However, predator response to …

The survival of a bird's developing embryo depends on the egg's ability to stay within strict
thermal limits. How eggshell colours help maintain thermal balance is a long-standing and …

Poor reproductive success has contributed to the decline and low population size of the
federally listed Western Snowy Plover (Charadrius alexandrinus nivosus), especially where …

Облигатный гнездовой паразитизм зарегистрирован менее чем у 1% видов мировой
фауны птиц. Столь небольшое число видов, для которых характерен такой способ …

For many birds, the fight for survival begins at the egg stage: avoiding predation is
paramount. At a broad phylogenetic level, selection by predators for egg camouflage …

Predation selects against conspicuous colors in bird eggs and nests, while thermoregulatory
constraints select for nest-building behavior that regulates incubation temperatures. We …
