Delayed plumage maturation and delayed reproductive investment in birds
GL Hawkins, GE Hill, A Mercadante - Biological Reviews, 2012 - Wiley Online Library
Delayed plumage maturation is the delayed acquisition of a definitive colour and pattern of
plumage until after the first potential breeding period in birds. Here we provide a …

Genomic and morphological analysis of a semipermeable avian hybrid zone suggests asymmetrical introgression of a sexual signal
Hybrid zones are geographic regions where differentiated taxa meet and potentially
exchange genes. Increasingly, genomic analyses have demonstrated that many hybrid …

Coordination between the sexes for territorial defence in a duetting fairy-wren
In territorial songbirds both sexes depend on possession of a territory, yet its defence is
traditionally regarded as the domain of male birds. Studies on duetting species have …

Multiple benefits of cooperative breeding in purple‐crowned fairy‐wrens: a consequence of fidelity?
Kin selection is one of the mechanisms that can explain apparent altruism by subordinate
individuals in cooperatively breeding species, if subordinates boost the production of kin …

Testosterone coordinates gene expression across different tissues to produce carotenoid-based red ornamentation
Carotenoid pigments underlie most of the red, orange, and yellow visual signals used in
mate choice in vertebrates. However, many of the underlying processes surrounding the …
