Nine species that breed locally, with some unknown proportion still in transit, comprised 1113 observations: American Redstart
, Warbling Vireo, Baltimore Oriole, Bluegray Gnatcatcher, Yellow Warbler, Prothonotary Warbler, Red-eyed Vireo (Vireo olivaceus), Rose-breasted Grosbeak (Pheucticus ludovicianus), and Yellow-throated Vireo (Vireoflavifrons) (Table 5).
Song categories of other species (among them American Redstarts
dagger]) One American redstart
infested with a single Amblyomma longirostre nymph.
1980) examined the age structure of breeding American Redstarts
(Setophaga ruticilla) represented in museum collections, and interpreted the significant difference in the proportion of yearlings collected east and west of the Great Plains as the result of a regional shift in molting chronology.
Interspecific competition and the niche of the American Redstart
(Setophaga ruticilla) in wintering and breeding communities.
Its sleek body and the bright red patches on its wings and tail serve as a kind of avian shorthand that says, "male American redstart
in prime breeding condition.
The mature deciduous forests of the state provide nesting habitat for the ovenbird, American redstart
, and cerulean, hooded, Kentucky and worm-eating warblers.
The American redstart
is one of the most abundant warblers in North America.
and black-throated blue warblers pecked around in the undergrowth.
Patterns and correlates of extrapair paternity in American Redstarts
To examine this, the Smithsonian scientists focused on American redstarts
(Setophaga ruticilla), a member of the warbler family, at a non-breeding site in Jamaica where they conduct long-term studies.
Like bright jewels flitting about from tree limb to tree limb, yellow-rumped, black-throated blue, orange blackburnian warblers and American redstarts
add their colors to the palette of the woods.
Others: American redstarts
(eastern half of the country and upper Midwest), common yellowthroats (throughout the United States) and yellow-rumped warblers (throughout most of the country except in areas of the Midwest)
According to a recent study by Peter Marra of the Smithsonian Migratory Bird Center, American redstarts
wintering in prime Jamaican mangrove habitat go on to have better reproductive success than those using less desirable scrublands.
4 Science, the researchers report that American redstarts
that reach their New Hampshire summer breeding ground early--a big factor in nesting success--have isotope ratios typical of moist, food-rich winter habitats.
