• The effect of coccidial infection on iridescent plumage coloration in wild turkeys (2005, background): “Similarly, coccidia in the genus Isospora have been shown to depress expression of carotenoid but not melanin coloration in the plumages of cardueline finches (Hill & Brawner 1998; Brawner et al. 2000; McGraw & Hill 2000).”
• How coccidian parasites affect health and appearance of greenfinches (2004, background): “Nothing is known about strain specificity of avian Isospora, although similarly to those of this study, the results of Brawner et al. (2000) and McGraw & Hill (2000) suggest that health impact of experimental infection can be induced in already infected individuals.”
• Parasites, testosterone and honest carotenoid-based signalling of health (2007, background): “Diseased and parasitized individuals allocate fewer carotenoids to their ornaments not only because parasites reduce carotenoid availability but also because these individuals need them as antioxidants and for resisting parasites (e.g. Thompson et al. 1997; Brawner et al. 2000).”
• Leukocyte Profiles in Wild House Finches with and without Mycoplasmal Conjunctivitis, a Recently Emerged Bacterial Disease (2004, background): “mycoplasmal conjunctivitis, Brawner et al. (2000) found that captive male House Finches that were infected with MG while completing their prebasic molt did not develop their normal plumage coloration.”
• Carotenoid accumulation strategies for becoming a colourful House Finch: analyses of plasma and liver pigments in wild moulting birds (2006, background): “These include parasites ( Brawner et al. 2000 ), general nutrition (Hill & Montgomerie 1994; Hill 2000) and hormone titres (Stoehr & Hill 2001), in addition to the amounts (Hill et al. 2002) and types of dietary carotenoids.”
• Testosterone, immunocompetence, and honest sexual signaling in male red grouse (2004, result): “Other studies nevertheless, have showed that infection by intestinal nematodes and coccidia can reduce levels of sexual signaling, such as comb size (Zuk et al., 1990a,b) or carotenoid-based color intensity ( Brawner et al., 2000; Hill and Brawner, 1998).”
• 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).”
• Testosterone and melanin-based black plumage coloration: a comparative study (2008, background): “…mate with males with more red in their plumage (Hill 1990), unless we understand that the red color is derived from carotenoid pigments by a process that is sensitive to both nutritional condition (Hill and Montgomerie 1994) and endoparasitic infections (Brawner et al. 2000; McGraw and Hill 2000).”
