Wherever their ranges overlap, Blue-winged and Golden-winged warblers are known to regularly hybridize. Hybridization with Blue-winged Warbler. Shifting geographic ranges have brought Blue-winged and Golden-winged … “It’s extremely rare,” said lead author David Toews, postdoctoral associate at Cornell Lab of Ornithology. Abundance. Blue-winged Warbler/Golden-winged Warbler), where for F1 hybrids interspecific heterozygosity is equal to one. Two different forms of hybrid between Blue-winged and Golden-winged Warblers were separately named as distinct species, Brewster's Warbler and Lawrence's Warbler in 1874. The research supports a model proposed by John T. Nichols of the American Museum of Natural History back in 1908 that the Brewster’s form of Golden- and Blue-winged warbler hybrids is an expression of dominant traits, and the Lawrence’s form is a recessive trait expression. The breeding male Blue-winged Warbler is unmistakable. “This way we could re-create what the hybrid’s mother would have looked like – the avian equivalent of a detective’s facial composite, but generated from genes. In North America, hybrids of Blue-winged and Golden-winged warblers have a mixture of plumage characteristics from each species. The wings are gray with two white bars, and there is a black eye stripe. Winters in Central America. Information about the classification of pinus. Blue-winged / Golden-winged warbler hybrids in Michigan. Researchers at Penn State have narrowed down the region of the genome that drives the black color in throat and face of warblers by studying the hybrid offspring of golden-winged and blue-winged warblers. Golden-winged warblers are also thought to be threatened by displacement and hybridization due to expanding ranges of blue-winged warblers : in many locations, golden-winged warblers have been replaced by hybrids and subsequently by blue-winged warblers . A lot of birds will end up interbreeding and then creating hybrids that diversify the … Hybridization is common among golden-winged and blue-winged warblers, leading to concern that the golden-winged will be hybridized out of existence. The yellow color of warblers, however, has a more complex genetic basis and raises concerns about how hybrids of these species are classified. Short says, "This tremendous variation again stresses that The hybrids of golden-winged and blue-winged warblers have a mix of coloration from the parent species, which allows researchers to identify which regions of … Blue-gray wings with two whitish wingbars; sharply pointed bill. She then mated with a chestnut-sided warbler and successfully reproduced.”. Blue-winged, Golden-winged, and Brewster's Warblers by Liz Clayton Fuller; Chestnut-sided Warbler from del Hoyo et al. Here are some of the coolest hybrids: Brewster’s and Lawrence’s Warblers (Golden-winged x Blue-winged Warbler) When a golden-winged warbler makes whoopee with a blue-winged warbler, the results aren’t always the same: you get a Brewster’s or a Lawrence’s warbler, depending on the genetic makeup. Females are duller, but otherwise similar. The Blue-winged Warbler's breeding range is moving farther northeast each year into the Golden-winged Warbler's breeding territory. Scientists are going to keep an eye on this location to see what the future may hold for this very rare bird. Although the bird is not especially shy, it can be a challenge to observe as it forages actively in the dense brush. Hybridizes with Golden-winged Warbler. Video by a bird watcher and eBird user Lowell Burket of Roaring Spring, Pennsylvania, recorded a male bird that sang like a chestnut-sided warbler but had some of the physical characteristics of blue-winged and golden-winged warblers. Warbler (Vermivora chrysoptera), the Blue-winged Warbler (V. pinus) and their hybrids. Its range is extending northwards, where it is replacing the very closely related golden-winged warbler, Vermivora chrysoptera. These results are compared and their behavioral and evolu-tionary implications discussed. We confirmed that the mother would have looked like a Brewster’s warbler and the father was a chestnut-sided warbler.”. Its range is extending northwards, where it is replacing the very closely related Golden-winged Warbler, Vermivora chrysoptera. “It also tells us that wood-warblers in general have remained genetically compatible long after they evolved major differences in appearance.”. In this article, I present evidence for the northern expansion of the Blue-winged Warbler’s range in Michigan. The most commonly encountered hybrid is called Brewster’s Warbler, the product of a first-generation cross between a Blue-wing and a Golden-wing. Brewster-type and Lawrence- type hybrids (i.e., hybrids without and with face masks) were found for all values of the hybrid index, from 0 to 20. A female golden-winged/blue-winged warbler hybrid.
