Pennsylvania birder spotted a bird in life in his yard last fall – this was a hybrid of three species on two genera in one bird. He found a three-in-one fighter.
Natural hybrids can be a concern for conservation, as animals who are mating with the wrong species can be born sterile offspring or birds that nobody wants with them. It seems that one hybrid larvae found love, albeit with a bird from a completely different genus, which led to strange results.
"This tells us that warblers generally appear to be reproducibly compatible in millions of years of independent development," said Gizmodo Dave Toews, a postdoctoral associate at Cornell's Ornithology Laboratory. "Things that really define them, their different colors and their songs, are likely to impede obstacles and do not mix because they can not, but because they do not choose."
Birder Lowell Burket knew something strange that he came to an observation point on his property last month. The bird looked like a hybrid, which is well-known among birds called the Brewster buzzer, which is a mixture of golden winglets and blue winglets. But she sang like a bird from a different genus, called the chestnut sidewalk, and had a worm's signature worm on its side, a red patch.
Burket watched the bird several times and eventually sent an e-mail to researchers Cornell.
"I tried to make an e-mail sound a bit intellectual so as not to think I was a burning sensation," Burket told the Cornell Lab of Ornithology in a release. "They had photos and video help."
The attachment was first skeptical, with regard to all the false alarms it received – someone once told him that he had seen a hybrid descendant of dove and duck, when he actually only saw the common American coat. But she's been looking for a hybrid honey for a long time Vermivora a genus containing the blue skirt and gold wingblablers as well as their hybrid, and Setophaga a genus containing the chestnut side ridge.
Chestnut men chestnuts regularly fight Vermivora according to Biology Letters, is unclear how to work with women. A Burke report, supported by his knowledge of birds, proved to fit the bill.
Toews visited Burket. They made the bird in the net and took a sample of blood before they left it for free. So he analyzed the bird mitochondrial DNA and figured out what he was looking for – Vermivora a dark mother – he assumed that the golden wing was curly – he connected with the chestnut side trimmer. But when he shared his results with colleagues and followers of Twitter, he was asked to continue.
Mitochondrial DNA only stores information about the mother's genus, so I would not reveal whether the strange mother bird is hybrid alone or not.
Further testing showed that followers of Toews Twitter were right: the mother was hybrid alone. Burke's bird was thus three types and two genera in one bird. As it was possible to find out in Toews, this was the first record of a hybrid interspecies, reproduced with a bird from a different genus, according to a newspaper.
The existence of a three-in-one trumpeter does not teach us much, except that there has been an incredible mistake somewhere in the north. But hybrids are generally interesting for studying for conservation reasons – female birds can cross if they are small partners and could "do the best in a bad situation," the report says.
However, if other birds do not wish to mate with hybrids or if hybrids are sterile, offspring can be considered "wasted reproductive efforts" and "a deterioration in the number of populations".
It is unclear whether the three-in-one thorns managed to merge with another bird, or it could even paralyzed, even though this spring returned to Burke's patch.
Birds are looking for love. Sometimes, if they can not find the right partner, they have to be saved.[Biology Letters via Cornell Lab of Ornithology]
