Dietary carotenoids predict plumage coloration in wild house finches.
Carotenoid pigments are a widespread source of ornamental coloration in vertebrates and expression of carotenoid-based colour displays has been shown to serve as an important criterion in female mate choice in birds and fishes. Unlike other integumentary pigments, carotenoids cannot be synthesized; they must be ingested. Carotenoid-based coloration is condition-dependent and has been shown to b...
متن کاملVariation in Plumage Coloration of Northern Cardinals in Urbanizing Landscapes
—Biologists know relatively little of how one of the most important avian phenotypic signals, feather coloration, may be affected by anthropogenic changes resulting from urbanization. We examined the relationship between urbanization and carotenoid-based plumage color of Northern Cardinals (Cardinalis cardinalis) in 13 riparian forests distributed across a rural-to-urban landscape gradient in c...

متن کاملThe Utility of Plumage Coloration for Taxonomic and Ecological Studies
Plumage coloration in birds serve multiple purposes, including species recognition, sexual selection cues, and camouflage. Differences in plumage coloration can be used to infer evolutionary relationships, identify distinct taxonomic units, and characterize geographic variation. With the advent of electronic devices to quantify plumage coloration quickly and reliably, taxonomic or geographic di...

Senar, J.C. 1999. Plumage colouration as a signal of social status. In: Adams, N.J. & Slotow, R.H. (eds) Proc. 22 Int. Ornithol. Congr., Durban: 1669-1686. Johannesburg: BirdLife South Africa. In 1975 Rohwer proposed that variable plumage traits of wintering flocking birds evolved to signal individual dominance status. Evidence from more than 50 papers on the so-called status signaling hypothes...
