Sexually Selected Egg Coloration in Spotless Starlings
It has been recently proposed that the blue‐green coloration in eggs of many avian species may constitute a sexually selected female signal. Blue‐green color intensity would reflect the physiologicalExpand

Some parasite cuckoo species lay eggs that, to the human eye, appear to mimic the appearance of the eggs of their favourite hosts, which hinders discrimination and removal of their eggs by hostExpand

Dark nests and egg colour in birds: a possible functional role of ultraviolet reflectance in egg detectability
Owing to the conspicuousness of ultraviolet (UV) colour in dark environments, natural selection might have selected UV egg coloration because it would enhance egg detectability by parents in murkyExpand

Rapid increase in cuckoo egg matching in a recently parasitized reed warbler population
Parasitic cuckoos lay eggs that mimic those of their hosts, and such close phenotypic matching may arise from coevolutionary interactions between parasite and host. However, cuckoos may alsoExpand

BLUE AND GREEN EGG-COLOR INTENSITY IS ASSOCIATED WITH PARENTAL EFFORT AND MATING SYSTEM IN PASSERINES: SUPPORT FOR THE SEXUAL SELECTION HYPOTHESIS
Abstract Among several adaptive explanations proposed to account for variation in avian egg color, that related to sexual selection is of particular interest because of its possible generality.Expand

Sex recognition by odour and variation in the uropygial gland secretion in starlings.
1. Although a growing body of evidence supports that olfaction based on chemical compounds emitted by birds may play a role in individual recognition, the possible role of chemical cues in sexualExpand

Rejection of parasitic eggs in relation to egg appearance in magpies
The coevolutionary process between avian brood parasites and their hosts predicts that low intraclutch variation in egg colour appearance favours egg discrimination of parasite eggs by hosts. LowExpand

Dark Nests and Conspicuousness in Color Patterns of Nestlings of Altricial Birds
Nests of altricial birds exhibit variable spectral properties that may affect the efficacy (conspicuousness) of the colored begging traits that a nestling displays to its parents. Here we exploredExpand

Avian colour perception predicts behavioural responses to experimental brood parasitism in chaffinches
Hosts of cuckoos have evolved defences allowing them to discriminate and reject parasite eggs. Mechanisms of discrimination are mostly visually mediated, and have been studied using approaches thatExpand

Increased host tolerance of multiple cuckoo eggs leads to higher fledging success of the brood parasite
In birds, multiple parasitism is the laying of two or more eggs by one or more parasitic females in a single host nest. Several cognitive mechanisms may explain how multiple parasitism could affectExpand
