Most American Redstarts migrate south through North America and winter in Mexico, Central America, and northern South America. Feeding Behavior. The benefits to coffee farms that redstarts and other "coffee birds" provide have encouraged coffee farmers to adapt shade trees and adjacent forest patches in their farming practices as additional habitat for the birds. The redstarts feed almost exclusively on insects which are usually caught by flycatching. The female selects a site usually next to the trunk of a tree or in a crotch of a bush with several more-or-less vertical stems. Photo: Tom Warren/Audubon Photography Awards. Across their breeding range American Redstarts prefer moist, deciduous, second-growth woodlands with abundant shrubs. Normally 1 brood per season. Sometimes will use old nests of other birds. There is evidence for a skewed sex ratio that results in a surplus of unmated males.[13][14]. Although perhaps not as common as in the past, the redstart appears to be one of the most stable and abundant species of New World warbler; its numbers exceeded in total by the common yellowthroat, yellow warbler and yellow-rumped warbler, because of much wider natural breeding ranges in those species and perhaps exceeding those in sheer density within appropriate range. Males sometimes mate with more than one female and raise 2-3 broods simultaneously. It is often found in shade-grown coffee plantations, which provide native trees and shrubs, as well as coffee trees. True to its Halloween-themed color scheme, the redstart seems to startle its prey out of the foliage by flashing its strikingly patterned tail and wing feathers. Although perhaps not as common as in the past, the redstart appears to be one of the most stable and abundant species of New World warbler; its numbers exceeded in total by the common yellowthroat, yellow warbler and yellow-rumped warbler, because of much wider natural breeding ranges in those species and perhaps exceeding those in sheer density within appropriate range. Climate threats facing the American Redstart. At times it feeds more like a flycatcher than a typical warbler, hovering among the foliage and often flying out to grab insects in mid-air. Or take action immediately with one of our current campaigns below: The Audubon Bird Guide is a free and complete field guide to more than 800 species of North American birds, right in your pocket. Even within monogamous pairs, a high proportion of offspring—as many as 40%—are not fathered by the male of the pair. Three decades ago, scientists realized that protecting birds across their full annual cycle required working with everyone along the way. Adult males are black with bright orange wings, tail, and sides. Incubation by female only, 11-12 days. Celebrating Thirty Years of Partnering for Migratory Bird Conservation, This Little Warbler Could Lead to Big Discoveries About Migration. Bald Eagle. 4, sometimes 2-5. Habitat. A lively warbler that hops among tree branches in search of insects, the male American Redstart is coal-black with vivid orange patches on the sides, wings, and tail. [15] Males are invariably very territorial and the superior males occupy the best habitats, such as moist mangroves, while inferior males occupy secondary habitats such as dry scrub forests. The breeding habitats of the redstarts are open woodlands or scrub, often located near water. American Redstart Information. The tail is often held partly fanned out. Their breast sides are also orange, with the rest of their underparts white. As the Climate Changes, How Will Birds Weather Heavier Rains and Snows? However, few survive past the first stages of life, as the bird is vulnerable to both terrestrial and aerial predators. or. The intensity of the male's coloration (which is due to carotenoid pigments) predicts their success at holding territory in their non-breeding, winter locations in the Caribbean, the probability that they will be polygynous, and the proportion of offspring in their nests that they will themselves father. Highest rates of predation occur during the breeding season when eggs and helpless nestlings are abundant and easy prey for varied predators. Aerial predators include jaegers, blue jays, common ravens, northern saw-whet owls, common grackles, northern goshawks, sharp-shinned hawks, and Cooper's hawks.[14][16]. During the breeding season, the redstart inhabits open-canopy, mostly deciduous forests, second growth, and forest edges. Leave the nest at 9 days old.
