Female American goldfinches use carotenoid-based bill coloration to signal status (2009, background): “Because yellow chroma is the best indicator of carotenoid deposition (Saks et al. 2003), we manipulated bill coloration of augmented-and dulled-bill models so that the yellow chroma of manipulated bills resembled those of females with the most, or least, colorful bills, respectively, in the…”
How coccidian parasites affect health and appearance of greenfinches (2004, methodology): “Variation in the average carotenoid concentration of the yellow area of tail feathers explained 32–51% of the variation of in these colour parameters (Saks et al. 2003).”
The size of the red wing spot of the American rubyspot as a heightened condition-dependent ornament (2008, methodology): “…these color properties based on color perception findings in other animals, which have been shown to ultimately affect behavioral decisions (e.g., mammals, Krupa and Geluso 2000; birds, Saks et al. 2003; reptiles, Whitting et al. 2006; fish, Marshall et al. 2003; insects, Katsoyannos et al. 1985).”
Carotenoid accumulation strategies for becoming a colourful House Finch: analyses of plasma and liver pigments in wild moulting birds (2006, background): “…biochemical basis of carotenoid coloration has been investigated (e.g. American Goldfinch [Carduelis tristis], McGraw & Gregory 2004; Greenfinch [Carduelis chloris], Saks et al. 2003), birds tended to accumulate more of all types of carotenoids within a fluid/tissue type (e.g. plasma, feathers).”
How feather colour reflects its melanin content (2005, result): “in House Finches, Carpodacus mexicanus, Inouye et al. 2001; Greenfinches, Carduelis chloris, Saks, McGraw & Horak 2003; American Goldfinches, Carduelis tristis, McGraw & Gregory 2004), and there are a few interesting contrasts between these studies and ours that deserve attention.”
