Paternal care as a conditional strategy: Distinct reproductive tactics associated with elaboration of plumage ornamentation in the house finch (2002, background): “In male house finches (Carpodacus mexicanus), elaboration of carotenoid ornamentation of breast plumage (Figure 1) is directly influenced by individual physiological condition, health status, and parasite exposure at the time of molt (Brawner et al., 2000; Hill, 2000).”
CAROTENOID PIGMENTS IN MALE HOUSE FINCH PLUMAGE IN RELATION TO AGE, SUBSPECIES, AND ORNAMENTAL COLORATION (2001, background): “There is evidence that nutritionally stressed House Finches produce less red plumage than birds that are not stressed even when they have access to the same carotenoid pigments (Hill 2000).”
Melanin- versus carotenoid-based sexual signals : is the difference really so black and red? (2006, methodology): “Future work examining proximate relations between diet and signalling needs to be careful to avoid simply manipulating overall condition, and will need to adopt a more sophisticated approach such as that used by Hill (2000) (discussed above).”
Pay-offs and penalties of competing migratory schedules (2003, background): “Hill (2000) calls attention to the energetic demand associated with achieving 288 OIKOS 103:2 (2003) maximal redness.”
The physiological costs of being colourful: nutritional control of carotenoid utilization in the American goldfinch, (2005, unknown): “Most notably, Hill (2000) found that experimentally induced food deprivation decreased the expression of carotenoid-based plumage coloration in male house ﬁnches, Carpodacus mexicanus , independent of the amount of carotenoids acquired from the diet.”
How coccidian parasites affect health and appearance of greenfinches (2004, background): “As pointed out by Hill (2000), the details of all these processes remain virtually unstudied but clearly there exists the potential for nutritional stress, independent of carotenoid availability to affect plumage coloration of birds.”
Diet quality affects an attractive white plumage pattern in dark-eyed juncos (Junco hyemalis) (2007, background): “…ornaments (Jawor and Breitwisch 2003; Veiga and Puerta 1996) as well as to structural coloration, which is produced by specialized nanostructure in feather keratin (Doucet 2002; Keyser and Hill 1999, 2000; McGraw et al. 2002; Prum et al. 1998, 1999; Shawkey et al. 2003; Siefferman and Hill 2003).”
Dietary carotenoid pigments and immune function in a songbird with extensive carotenoid-based plumage coloration (2003, methodology): “Water was supplemented with sulphadimethoxine (0.12 g/L water), to suppress Isosporan coccidiosis, an ubiquitous disease of goldfinches that will quickly kill aviary birds (McGraw and Hill, 2000).”
A melanin-based trait reflects environmental growth conditions of nestling male Eurasian kestrels (2007, background): “Bird studies indicate that both carotenoid- (Hill 1999; 2000; Senar et al. 2003; Tschirren et al. 2003) and structurally based (Gustafsson et al. 1995; Keyser and Hill 1999) ornamental colours are energetically and nutritionally demanding to produce.”
MELANIN ORNAMENTS, HONESTY, AND SEXUAL SELECTION (2003, methodology): “Gray (1996) and Badyaev and Hill (2000) have proposed that lack of sexual dimorphism in melanin ornaments in contrast to carotenoid ornament dimorphism is evidence against sexual selection of melanin ornaments.”
How feather colour reflects its melanin content (2005, background): “2001), and this knowledge has been important for targeting how the honesty of these signals is reinforced (Hill 2000).”
Variation in spectral reflectance among populations of Dendrobates pumilio, the strawberry poison frog, in the Bocas del Toro Archipelago, Panama (2003, background): “These models assume that production of the indicator trait is inherently costly, and that variation in the cost of production (e.g. pigment scarcity) can lead to variation in the expression of the trait (Hill, 1994, 2000; Grether, 2000).”
Do sexual ornaments demonstrate heightened condition-dependent expression as predicted by the handicap hypothesis? (2004, background): “ Hill (2000) found that food stress modulated the ability of male house finches (Carpodacus mexicanus) to process different carotenoids from the diet into plumage coloration.”
The effect of coccidial infection on iridescent plumage coloration in wild turkeys (2005, background): “It is becoming increasingly clear, however, that colour ornaments produced by different mechanisms can serve as fundamentally different types of displays, each with a distinct signal content (e.g. Owens & Hartley 1998; Badyaev & Hill 2000).”
Evolution of sexual dichromatism: contribution of carotenoid- versus melanin-based coloration (2000, background): “In contrast, melanin pigments are constructed from resources that are not limiting for most animals (Nickerson, 1944; Rawles, 1959; Bowers, 1988) and their expression is not generally affected by condition (Brawner, 1997; Hill & Brawner, 1998; Hill, 2000; but see Veiga, 1995).”
Carotenoid accumulation strategies for becoming a colourful House Finch: analyses of plasma and liver pigments in wild moulting birds (2006, methodology): “…to the important red carotenoid pigments (e.g. 3-hydroxy- echinenone) in plumage, and as suggested by several prior studies some males better than others must also complete these important metabolic, condition-dependent conversions en route to becoming sexually attractive (e.g. Hill 2000).”
