Bird Hybrid discovered in Pennsylvania Yard is three types in one, DNA test reveals



The yellow, black and white birds observed in the yard in Pennsylvania earlier this year showed a hybrid of three different types.

When bird watcher Lowell Burket saw a male bird in Ruganje Spring municipality in May, he noticed that he had physical features of a blue wing and a golden wing, Huffington Post reported. The bird, however, sang as the third species.

After capturing bird photos and videos, Burket contacted Fuller's Cornell Evolutionary Biology Lab. The lab had happily noticed his email, and researcher David Toews contacted him

The two took blood samples and measured the birds when they found it again. The DNA analysis now reveals that Burket's doubt about the bird was right.

There are three types in one. The mother of the bird was a hybrid between the blue wing and the golden wing, while the father was a chestnut.

In a statement released by Cornell's Ornithology Laboratory, Toews explained that they were watching genes that code different battalions to create what a bird would look like. He explained that this is the avian equivalent of the detective complex of facial genes with the aid of the gene.

This hybrid bird seen in Pennsylvania is three types in one.

Hybridization usually occurs between blue and gold wings, but before Burket's discovery, hybridization has not been observed between these species and chestnut wool fibers.

"It's extremely rare," said Toews. "The woman is a hybrid golden wings / blue wings, also known as Brewster's pins, and then moved away with a chestnutian one-way twist and successfully reproduced."

This type of hybridization is a rare occurrence, but may occur more frequently in the warbler population decline due to the smaller pool of friends you can choose.

Toews explained that hybridization in the declining population of golden winged warriors suggests that female species might be the best in a bad situation.

Toews also said that it suggests warblers are generally reproducibly compatible long after they have independently developed great differences in appearance.

"This tells us that warriors generally seem reproducibly compatible over millions of years of independent evolution," said Toews. Gizmodo.

"What really defines them, their different colors and their songs, are likely to mingle barriers, and not cross because they can not, but because they do not want it."

The findings were published in the journal Biology of letters November 7th.
