Sexually Selected Egg Coloration in Spotless Starlings
TLDR
A negative relationship between the effect of experimental food supply on nestling immunocompetence and the intensity of blue‐green coloration of eggs is found, suggesting that egg color predicts nutritional conditions that nestlings will experience during development.

Dark nests and egg colour in birds: a possible functional role of ultraviolet reflectance in egg detectability
TLDR
The hypothesis that UV egg colours are designed to provide highly detectable targets for parent birds in dark nest environments is tested by using comparative and experimental approaches and results are consistent with the hypothesis.

Rapid increase in cuckoo egg matching in a recently parasitized reed warbler population
TLDR
Tests for temporal change in degree of matching between eggs of the parasitic European cuckoo and its reed warbler host during 24 consecutive years in a recently parasitized reedwarbler population provide tentative support for the cuckoos preference hypothesis suggesting that cuckOO‐host egg matching could partially be due to cuckoff females selecting host nests based on the appearance of their eggs.

Egg colour mimicry in the common cuckoo Cuculus canorus as revealed by modelling host retinal function

TLDR
Cuckoo races as assessed by humans do not entirely match with host perception of matching and that achromatic mechanisms could play a main role in the discrimination of cuckoo eggs at low-light levels.

BLUE AND GREEN EGG-COLOR INTENSITY IS ASSOCIATED WITH PARENTAL EFFORT AND MATING SYSTEM IN PASSERINES: SUPPORT FOR THE SEXUAL SELECTION HYPOTHESIS
TLDR
It is proposed that because biliverdin is an antioxidant, deposition in the eggshell by laying females may signal the capacity of females to control free radicals, despite the handicap of removing this antioxidant from their body.

The heterospecific habitat copying hypothesis: can competitors indicate habitat quality?
TLDR
Two results suggest that the use of heterospecific public information in breeding habitat selection may be at work: an increase in the reoccupancy probability by kestrels of previous roller nests with increasing nest success, and an increased in roller breeding population with increasing local kestREL success.

Avian colour perception predicts behavioural responses to experimental brood parasitism in chaffinches
TLDR
A perceptual model of colour discrimination is applied to study behavioural responses to natural variation in parasite egg appearance in chaffinches Fringilla coelebs and confirms that colour differences of the eggs as perceived by birds are important integral parts of a matching signal used by chaffinch hosts.

Sex recognition by odour and variation in the uropygial gland secretion in starlings.
TLDR
This study reveals for first time that a passerine species can discriminate the sex of conspecifics by relying on chemical cues and suggests that the uropygial gland secretion may potentially function as a chemical signal used in mate choice and/or intrasexual competition in this species.

Dark Nests and Conspicuousness in Color Patterns of Nestlings of Altricial Birds
TLDR
Findings are consistent with a scenario in which selection for nestling detectability in dark environments has favored the evolution of particular achromatic components of gape coloration but also nestling traits that enhance signal efficacy by maximizing color contrasts within a nestling.

The value of nestboxes in the conservation of Eurasian Rollers Coracias garrulus in southern Spain
The installation of nestboxes is a widely used conservation measure for enhancing habitat suitability for cavity-nesting birds wherever natural holes are scarce. However, nestboxes may attract birds…
