• Physiological mechanisms mediating costs of immune responses: what can we learn from studies of birds? (2012, background): “Note also that glucocorticoids (Fowles et al. 1993; Evans et al. 2000; Owen-Ashley et al. 2004; Roberts et al. 2004) and heat shock proteins (Merino et al. 2001; Morales et al. 2006; but see Garamszegi et al. 2006) have been found to correlate negatively with immune responses in wild birds.”
• Female American goldfinches use carotenoid-based bill coloration to signal status (2009, background): “In contrast, melanin signals are thought to be favored as signals of status because they are often testosterone-limited (Evans et al. 2000), and hence, their expression can be directly linked to physiological allocation that enhances aggressiveness.”
• Social environment during molt and the expression of melanin-based plumage pigmentation in male house sparrows (Passer domesticus) (2002, background): “Evans et al. ( 2000) and Gonzalez et al. ( 2001) recently tested the effect of experimentally elevated T on the expression of melaninbased plumage pigmentation in male house sparrows and found that males with high androgen levels grew larger patches of melanin-based plumage.”
• Ectoparasites of house sparrows (Passer domesticus): an experimental test of the immunocompetence handicap hypothesis and a new model (2000, background): “It may depress immunocompetence directly (Grossman 1985; Zuk et al. 1995; Salvador et al. 1996; Evans et al. 2000 ) through reducing the circulating levels of IgY (humoral response) (Barnard et al. 1993), caused by reduced production of B-lymphocytes in the bursa of Fabricius (Zuk et al. 1995; Salv”
• Immune response covaries with corticosterone plasma levels under experimentally stressful conditions in nestling barn swallows (Hirundo rustica) (2003, background): “…large corticosterone plasma levels, together with the negative covariation between immune response and corticosterone levels after long-term stress, corroborates the idea of an immunodepressive effect of corticosterone (see Apanius, 1998; Evans et al., 2000; Poiani et al., 2000; von Holst, 1998).”
• Maternal yolk testosterone does not modulate parasite susceptibility or immune function in great tit nestlings (2005, unknown): “In house sparrows (Passer domesticus), implantation of testosterone in adult males led to lower secondary immune response ( Evans, Goldsmith & Norris 2000 ).”
• Dietary amino acids influence plumage traits and immune responses of male house sparrows, Passer domesticus, but not as expected (2005, background): “Social interactions could also have directly affected moult, perhaps by altering hormone profiles (Evans et al. 2000; Buchanan et al. 2003) or otherwise affecting the stimulation of melanocytes in feather follicles.”
• Condition and androgen levels: are condition-dependent and testosterone-mediated traits two sides of the same coin? (2006, background): “Although the proximate control of testosterone on plumage trait expression has been demonstrated in some species (Evans et al. 2000; Peters et al. 2000) it does not seem to be a general rule (Kimball & Ligon 1999).”
• Immune challenge mediates vocal communication in a passerine bird: an experiment (2004, background): “Additionally, contradictory results may appear owing to the possible confounding effects of other hormones such as corticosterone, which potentially mediates the relationship between testosterone and immunocompetence (Duffy et al., 2000; Evans et al., 2000).”
• The Physiology of Life History Trade-Offs in Animals (2001, background): “Testosterone could affect immune function indirectly via corticosteroids (Evans et al. 2000, Castro et al. 2001).”
• Testosterone and melanin-based black plumage coloration: a comparative study (2008, background): “…wellstudied example of house sparrows, as detailed in “Introduction,” demonstrates that among-male differences in melanization can be affected by among-male differences in T (Evans et al. 2000; Buchanan et al. 2001; González et al. 2001) even if plumage dichromatism itself is under genetic control.”
• MELANIN ORNAMENTS, HONESTY, AND SEXUAL SELECTION (2003, background): “In House Sparrows, the area of the black bib is enlarged by testosterone during molt (Gonzalez et al. 1999, Evans et al. 2000, Gonzalez et al. 2001), but whether the ratio of the two types of melanins is affected is not known.”
• How feather colour reflects its melanin content (2005, background): “Since melanin colours are widely seen as testosteronedependent ( Evans, Goldsmith & Norris 2000 ) badges of status in avian societies (Senar 2006), it is tempting to link these studies and suggest a common mechanistic link between pigment accumulation and signal function.”
• Testosterone, dominance signalling and immunosuppression in the house sparrow, Passer domesticus (2003, background): “Our data therefore lend some support to the hypothesis that it is corticosterone, not T, which directly exerts the cost associated with the development of sexual traits (Evans et al. 2000) or that corticosterone and T work in tandem to facilitate immunosuppression.”
