“…Feather growth has been shown to be maintained in preference to, or even at the expense of, muscle development in turkeys when feed availability was restricted ( Wylie et al, 2001 ). As such, under natural conditions feather growth and the maintenance of feather quality is energetically costly and thought to be an indicator of an individual’s condition (Falconiformes: Bortolotti et al, 2002 ; Passerines: Bulluck et al, 2017 ; Hill and Montgomerie, 1994 ; Review: Jovani and Rohwer, 2017 ), and the quality of their environment (Charadriiformes: Patterson et al, 2015 ; Will et al, 2014 ; Passerines: DesRochers et al, 2009 ; Lattin et al, 2011 ; Swaddle and Witter, 1994 ). Aspects of plumage condition are thought to act as honest signals in a variety of social contexts including mate selection (Passerines: Hill, 1990 , 1991 ; Siefferman et al, 2005 ) signals of social status ( Passer domesticus: Nakagawa et al, 2007 ) and parent-offspring communications (Passerines: Tanner and Richner, 2008 ; Psittaciformes: Griggo et al, 2009 ).…”

“…Several studies have found that female coloration is important in male mate choice [75,76], reproductive success ([77–79], but see [80]), and parental care [79]. Females of several dichromatic species display ornamentation that is similar to males, but often reduced in intensity or extent [32,34].…”

Lack of conspecific visual discrimination between second-year males and females in the Saffron Finch

Sexually dichromatic birds often show delayed plumage maturation, but second-year (SY) males may or may not be distinguishable from females. In competitive contexts, SY males receive a reduced amount of adult males’ aggression, either by mimicking females or through signaling their sex and inexperience as subordinate males. To the human eye, reproductive dull SY male Saffron Finches are indistinguishable from females, whereas after second-year (ASY) males are golden yellow. Our aim is to establish whether SY males are sexually dichromatic with females to the eye of conspecifics. We describe plumage variation in females, SY and ASY males and, in particular, analyze assortative mating by color by comparing a previously disregarded yellow feather patch shared by the three groups. We measured plumage reflectance of the forehead, breast, belly, and axillaries, and used a two-step avian visual model analysis to estimate the ability of Saffron Finches to distinguish between SY males and females. We find that those groups are indistinguishable to conspecifics by color. Furthermore, we find non-significant evidence of assortative mating directly related to the coloration of comparable feather patches between females and each type of male, though body condition of SY males is associated to that of their mates. Our results are compatible with both the female-mimicry and the status signaling hypotheses of evolution and maintenance of delayed plumage maturation. However, the singing behavior of males reveals their presence within the breeding site; the combined effect of song and dull coloration suggest that SY males are honestly revealing their sex and status to conspecifics.

“…Although this molt schedule is not unusual for shorebirds (Lourenço and Piersma 2015) and waterfowl (e.g., Clark et al 2014; considered ''prebasic molt'' in updated terminology for waterfowl; Pyle 2005), it has not The Condor: Ornithological Applications 120:507-516, Q 2018 American Ornithological Society been described in the literature for Passeriformes. Nearly all migrant passerines studied to date that undergo a partial prealternate molt have been found to do so on the wintering grounds (e.g., Mowbray 1997, Mazerolle et al 2005, Boone et al 2010, Bulluck et al 2017, with individuals only occasionally continuing this molt during migration (E. Johnson personal communication). However, given the paucity of studies on the spatial ecology of molt, it seems likely that this strategy occurs elsewhere in Passeriformes, and even in Icteridae.…”

ABSTRACTTo achieve greater understanding of the full annual cycles of birds, it is critical to describe the spatial nature of littleunderstood phases. One of the least understood aspects of avian annual cycles is the ecology of molt: the periodic replacement of feathers. While work on the spatial nature of molt in migratory passerines has increasingly found incidences of species and populations completing molt during migration, this work has been limited entirely to prebasic flight feather molt. We examined the prevalence and progression of contour feather molt in a migratory songbird, the Rusty Blackbird (Euphagus carolinus), during spring stopover. We found that 98% of birds exhibited a partial prealternate molt during stopover, primarily in the head region. Furthermore, molt intensity peaked in the middle of the migration period and was negatively associated with fat score. This is the first evidence in the passerine literature of an obligate prealternate molt completed during migration, which is in many ways similar to the molt strategy of a variety of shorebirds (Families Charadriidae and Scolopacidae). These findings could prove crucial to understanding the constraints on spring migration in this declining species. Furthermore, we argue that molt schedules such as those of the Rusty Blackbird and shorebirds should be referred to as ''prealternate molt-migration,'' broadening the traditional definition of molt-migration beyond prebasic flight feather molt.Preuve d'une mue prénuptiale-migration chez un passereau RÉSUMÉ Afin de mieux comprendre les cycles annuels complets des oiseaux, il est essentiel de décrire la nature spatiale des phases encore mal connues. L'un des aspects les moins bien compris des cycles annuels des oiseaux est l'écologie de la mue : le remplacement périodique des plumes. Alors que les travaux sur la nature spatiale de la mue chez les passereaux migrateurs ont fourni de plus en plus de preuves que des espèces et des populations complètent la mue durant la migration, cesétudes se sont limitéesà la mue postnuptiale des plumes de vol. Nous avons examiné la prévalence et la progression de la mue des plumes de contour chez un oiseau chanteur migrateur, Euphagus carolinus, au cours d'une halte migratoire au printemps. Nous avons trouvé que 98 % des oiseaux présentaient une mue prénuptiale partielle au cours de la halte migratoire, prin...
