A melanin-based trait reflects environmental growth conditions of nestling male Eurasian kestrels (2007, background): “The recent avalanche of bird studies focused on the expression and function of melanin-based (e.g. González et al. 2001; Jawor and Breitwisch 2003; Roulin et al. 2003a; Badyaev and Young 2004; Roulin 2004a), carotenoid-based (e. g. Hill 1999; Badyaev and Young 2004; Blanco et al. 2005) and…”
Pleiotropy in the melanocortin system, coloration and behavioural syndromes. (2008, unknown): “+ House sparrow (Passer domesticus)[14]”
Female American goldfinches use carotenoid-based bill coloration to signal status (2009, background): “Because the honesty of status signals is thought to be partially maintained by the negative physiological effects of testosterone (Gonzalez et al. 2001), such as immunosuppression (Folstad and Karter 1992), selection should be expected to favor both carotenoid and melanin signals of status.”
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.”
Testosterone, dominance signalling and immunosuppression in the house sparrow, Passer domesticus (2003, background): “However both theoretical (Johnstone and Norris 1993) and empirical work (Gonzalez et al. 2001) suggest that frequent testing alone is not sufficient to maintain the honesty of the signalling system, suggesting the need for other costs associated with advertisement.”
Social environment affects female and egg testosterone levels in the house sparrow (Passer domesticus) (2003, unknown): “The determination of testosterone concentration in egg yolk and in plasma follows standard radioimmunoassay techniques (Lormée et al. 2000; Gonzalez et al. 2001; Mazuc et al. 2003).”
Testosterone upregulates lipoprotein status to control sexual attractiveness in a colorful songbird (2006, background): “Other types of avian pigment-based ornaments, such as black melanic coloration (Ros 1999; Evans et al. 2000; Gonzalez et al. 2001) and hemoglobinfilled wattles and combs (Zuk et al. 1995), are similarly known to deepen in color when T levels are high.”
Testing the immunocompetence handicap hypothesis: A review of the evidence (2004, background): “Testosterone is positively related to badge size in house sparrows, Passer domesticus (Evans et al. 2000; Buchanan et al. 2001; Gonzalez et al. 2001), and experimental results suggest that differences in feather abrasion, related to testosterone levels, also affect seasonal exposure of the badge (Go”
Condition and androgen levels: are condition-dependent and testosterone-mediated traits two sides of the same coin? (2006, background): “Although in many cases variation in body condition may be the most parsimonious explanation for variation in the expression of both secondary sexual traits and testosterone levels, many correlational studies do not control for this variable and focus only on the relation between testosterone and tra”
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.”
Seasonal changes in blue tit crown color: Do they signal individual quality? (2006, background): “2004) while house sparrows (Passer domesticus) with experimentally reduced testosterone levels kept their throat badge small through reduced abrasion of the buff feather tips concealing the black feathers (Gonzalez 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.”
Predation risk, host immune response, and parasitism (2004, background): “We captured house sparrows in mist nets during December 2000–January 2001 and September–October 2001 and put them in eight aviaries sized 3.5 3 1.1 3 2.5 m.”
Intraspecific preen oil odor preferences in dark-eyed juncos (Junco hyemalis) (2011, background): “2005), steroid hormone levels (Gonzalez et al. 2001; McGlothlin et al. 2008), immune function (Nolan et al.”
