All birds construct nests in which to lay eggs and/or raise offspring. Traditionally, it was
thought that natural selection and the requirement to minimize the risk of predation …

Camouflage is perhaps the most widespread anti-predator defense in nature, with many
different types thought to exist. Of these, resembling the general color and pattern of the …

The geometrical properties of eggs–such as volume and surface area–have uses ranging
from ecological, physiological and morphological studies in birds, to predictions of chick …

Camouflage is widespread throughout the natural world and conceals animals from
predators in a vast range of habitats. Because successful camouflage usually involves …

Deceptive antipredator defense mechanisms fall into three categories: depriving predators
of knowledge of prey's presence, providing cues that deceive predators about prey handling …

Camouflage is found in a wide range of species living in numerous habitat types, offering
protection from visually guided predators. This includes many species from the intertidal …

Physiological constraints on colouration have been widely reported; especially in birds,
which trade-off antioxidant responses against colourful costly signals. One female extended …

Camouflage conceals animals from predators and depends on the interplay between the
morphology and behaviour of animals. Behavioural elements of animals, such as the choice …

Ce travail de thèse explore les influences maternelles non génétiques chez un oiseau
nidifuge, la caille japonaise Coturnix c. japonica. Un premier axe s' intéresse à l'influence …

Crypsis is an antipredatory mechanism coupled to movement reduction, and in
consequence, it limits foraging opportunities. With the aim of determining if the diet of …
