Nowadays everyone can be obsessed with Mandarin duck in New York, but there is another bird worth your attention.
According to a report from Cornell Lab of Ornithology, a striking yellow, black and white bird seen in Pennsylvania is actually a hybrid between three different species.
The highly observant birdwatcher Lowell Burket saw the male bird in May in Roaring Spring. He realized that the bird had the physical characteristics of the blue-winged warbler and the golden-winged warbler, but sang the third species, like the chestnut-edged warbler. After capturing his photo and video, the bird showed enough interest in contacting the Fuller Evolutionary Biology Lab in Cornell.
”I didn't think there was a crack in the email so I tried to make his voice a little intellectual,“ he said.
Fortunately, the lab did not think the Burkete was a crack, and researcher David Toews soon contacted him. Together, they found the bird again and made blood samples and ID measurements.
Apparently, Burket's suspicion was right. DNA analysis showed that the father was a warbler with chestnut margins, while the bird's mother was a hybrid between the golden-winged warbler and the blue-winged warbler. The results of the analysis were published this week in the journal Science in Biology Letters.
The article states that the mixture is particularly important, because the mother and father of the bird are not only different species, but also different genera. Both gold and blue winged warriors are part of the genus Vermivora, while the chestnut-edged warblers are part of the genus Setophaga.
The researchers suspect that this three-way hybridization is, in conclusion, partly due to the decline in the local population of gold-winged warriors, and that women are separated by fewer potential friends. In response, the researchers wrote that durum do the best of a bad situation “by selecting people of their own species and genus.
As for the rare new hybrid, then we hope some hot weather.
“Bird is a [United States Geological Survey] The aluminum band was seen on the property until the end of August, and was not seen again,, Toews said in an email to HuffPost. ”Probably migrated south in winter!“
