We gathered data from 208 American Redstart (Setophaga ruticilla) nests from 1979 to 1985 in southwestern New Brunswick to examine patterns in nest-tree features. Most nests were located in either speckled alder (30.7%) or white birch (22.1%). Nest-site features (nest height, relative nest height, nest access distance) were relatively consistent for those nests located in some tree taxa (alder) but considerable intrataxa variability (cedar, white birch) and several significant intertaxa differences were observed. These differences may reflect each species' branching geometry. Our data were not entirely consistent with existing models of nest-height distribution.

Abstract We examined the hypothesis that territorial American Redstart (Setophaga ruticilla) males are geographically randomly distributed with respect to structure of the single song used predominantly before nesting. Present methods to assess the degree of similarity of song between neighboring birds are often inadequate because they do not give the level of statistical significance. We present a computer method to generate the appropriate null distribution from which the level of significance can be determined. We found statistically significant correlations between neighbors primarily in the last and penultimate discrete vocal items (phones) of the song. There were also important differences between the 2 samples.

Most studies investigating the function and evolution of ornaments have focused on males. Variation in ornaments may also reflect individual quality and convey information in females. We examined correlations between female plumage colour and reproductive variables in the sexually dichromatic songbird, the American Redstart (Setophaga ruticilla (L., 1758)). Female American Redstarts display yellow, carotenoid-based plumage patches on their tails, wings, and flanks. Using reflectance spectrometry, we quantified brightness (feather structure) and “yellowness” (hue and chroma) of tail and flank feathers to examine whether female plumage colour varies with age, reproductive success, parental care, and the plumage colour of mates. Female plumage varied with age, with adult (after-second-year) females having brighter tail feathers than first-year females. We failed to find a relationship between female plumage colour and pairing or first-egg dates. However, adult females with brighter tails visited their nests less frequently and first-year females with brighter tails fledged fewer offspring. Adult females with brighter tails also mated with males who provided less care. In addition, adult females with yellower flanks paired with males with brighter flanks and with males who provided less parental care. We suggest that plumage colouration in female American Redstarts can act as a signal of individual age and quality.
