We found no support for this hypothesis, suggesting that selection pressure for communal laying did not result in the diversity of conspicuousness found in avian eggs. Overall, we argue that future investigations of egg coloration should consider egg appearance (eggshell background colour and ...
Nest construction behavior that employs light-colored, thermally reflective materials may represent an evolutionary response by birds and other egg-laying organisms to egg predation and heat stress. 展开 关键词: Anti predation Charadrius melodus Egg crypsis Nest construction Thermoregulation ...

Both species start their incubation upon laying their last eggs. We determined the initiation of the incubation according to behaviors of breeding pairs, such as feeding by males, staying time of females in nests. When these behaviors were observed, we dug nest burrows (Ground Tits) and ...
Spot darkness, spread and ground colour diminished along the laying sequence, suggesting that the deposition of both pigments was limiting for females over the short term. Also, the proportion of eggs with biliverdin diminished in consecutive clutches laid by the same female over the breeding ...
