Indigo Bunting (Passerina cyanea) Science Article 1 abstract Habitat loss and fragmentation have led to a widespread increase in the proportion of edge habitat in the landscape. Disturbance-dependent bird species are widely assumed to benefit from these edges. However, anthropogenic edges may concentrate nest predators while retaining habitat cues that birds use to select breeding […]

MIGRATORY FEATURES OF THE INDIGO BUNTING IN JAMAICA AND FLORIDA
Indigo Bunting (Passerina cyanea) Science Article 5 abstract Recent years have seen the accumulation of many useful quan- titative and qualitative data pertaining to weight and fat in migratory birds. Most investigations of this nature have thus far dealt with birds breeding and overwintering on north temperate land masses, but few quantitative data pertaining to […]
Replaced primaries in first nuptial plumage of Passerina cyanea.
Indigo Bunting (Passerina cyanea) Science Article 3 abstract Dwight pointed out (1900, p. 211 et seq.) long ago that the Indigo Bunting replacessome outer primaries at the postjuvenal molt. These replaced primaries (in the male) have blue outer vanes contrasting sharply with the blackish outer vanes of the juvenal primaries, except that primary 9 has […]

Male Parental Care and Extrapair Copulations in the Indigo Bunting
Indigo Bunting (Passerina cyanea) Science Article 6 abstract Levels of parental care by male Indigo Buntings (Passerina cyanea) were predicted to be lower and the tendency to pursue extrapair matings greater when (1) the opportunity of additional matings (extrapair copulations) was high, (2) the male was cuckolded, and (3) the clutch or brood size was […]
FEMALE MATE CHOICE IN RELATION TO STRUCTURAL PLUMAGE COLORATION INBLUE GROSBEAKS
Blue Grosbeak (Passerina caerulea) Science Article 1 abstract Plumage blueness in Blue Grosbeaks (Passerina caerulea) is related to nutritional conditionduring molt, and bluer males hold larger territories with more food resources. We tested the hypothesis that females use male plumage brightness as a criterion in choosing mates. In a mate-choice aviary, we presented females with […]
Effects of breeding density and plumagecoloration on mate guarding and cuckoldry in bluegrosbeaks (Passerina caerulea)
Blue Grosbeak (Passerina caerulea) Science Article 3 abstract For species in which females mate outside of the pair bond, selection should favor male mate-guarding behaviors that minimize investment in genetically unrelated offspring. Mate guarding may impose costs by diverting time and energy from activities such as foraging and seeking extra-pair copulations, so males should adjust […]
