The first comprehensive review of all aspects of the biology of moult, drawing information
from across the literature and in all birds, from penguins to passerines. Feathers are …

Plumage ornaments act as important sexual signals, though the extent to which these
ornaments act as honest signals—and the physiological mechanisms that maintain honesty …

Many studies investigated variation in the frequency of extrapair paternity (EPP) among
individuals. However, our understanding of within-individual variation in EPP remains …

Plumage and song are important signals used by birds to attract mates and repel rivals.
Divergence in sexual signals can lead to reproductive isolation among incipient species, but …

The Hamilton–Zuk hypothesis predicts that ornament expression is a signal of the ability of
individuals to resist parasite infection. Thus, across a population (ie between‐individuals) …

Birds exhibit a vast array of colours and ornaments and while much work has focused on
understanding the function and evolution of carotenoid‐based colours (red, orange, yellow) …

We investigated moult strategies in Loggerhead Shrikes by examining first prebasic or
preformative moult patterns and by assessing the general location where individual feathers …

We investigated potential information content in red carotenoid-based undertail coverts of 28
pairs of breeding Great Spotted Woodpeckers by comparing plumage reflectance to …

A ornamentação da plumagem à base de carotenoides recebe atenção notável porque os
pigmentos carotenoides são adquiridos através da dieta. Isto levantou a ideia de que …

Color‐based visual signals are important aspects of communication throughout the animal
kingdom. Individuals evaluate color to obtain information about age and condition and to …
