Three Species of Hybrid One Species of Spotted Bird in Pennsylvania Backyard Reveals DNA Test



Earlier this year, a yellow, black and white bird seen in a backyard in Pennsylvania became a hybrid of three different species.

When Birdwatcher Lowell Burket saw the male bird in Roaring Spring district in May, he realized that he had the physical characteristics of the blue-winged warbler and the golden-winged warbler. Huffington Post It was reported. The bird, however, sang like a third species, chestnut-sided warbler.

After taking photographs and videos of the bird, Burket contacted the Fuller Evolutionary Biology Lab in Cornell. The laboratory soon realized that he had noticed his email and researcher David Toews contacted him.

When they found the two again, they took blood samples and bird measurements. DNA analysis now suggests that Burket's suspicion about the bird is correct.

There are three species in one. The bird's mother was a hybrid between the blue-winged warbler and the golden-winged warbler, while the father was a chestnut-edged cross.

In a press release issued by the Cornell Ornithological Laboratory, Toews explained that they look at genes encoding different warbler colors, so they can revive what the bird's mother will look like. He explained that this was the avian equivalent of the face composite of the detective generated with the help of genes.

This bird hybrid, seen in Pennsylvania, has three species in one.

Hybridization is commonly seen among the Blue-winged and Golden-winged Warblers, but before the Burket's discovery, hybridization between these species and Chestnut-sided warblers has not been recorded.

"Very rare," says Toews. Ir The female is a Golden-winged / Blue-winged Warbler hybrid – also called Brewster's Warbler. He was then paired with a Chestnut-edged Warbler and successfully replicated. "

Such a hybridization is a rare event, but may occur more often in the reduction of warbler populations because of a smaller mating pool.

Toews argued that the reduction in the population of the Golden-winged warriors could do the best of a bad situation in the females of hybridization.

It is also said that this situation argues that the fighters are generally compatible with the reproductive power after evolving the seemingly significant differences.

According to Toews, old Killers have the ability to reproduce in general throughout millions of years of independent evolution. Gizmodo.

Iy The things that really define them, their different colors and songs, are likely to overcome obstacles, and they can't, because they prefer it because they can't do it, they don't mix. Farklı
