Bird Hybrid Spotted in Pennsylvania Backyard has three species together, DNA test reveals


The yellow, black and white bird found in the backyard of Pennsylvania earlier this year turned out to be a hybrid of three different species.

When Bird Watcher Lowell Burket saw a male bird in May in the May Roaring Spring district, he noticed that it had a blue-eyed dwarf and golden poultry, Huffington Post reported. The bird, however, sang like a third species, a chestnut tree.

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

Two took blood samples and measurements of the bird when they found it again. DNA analysis now reveals that Burket suspect bird was right.

There are three types together. The bird's mother was a hybrid of a purple-blue dwarf and golden poultry, while the father was a chestnut tree.

In a press release published by Ornithology Cornell Lab, Toews explained that they looked at the genes that code the different guy colors in order to create what the bird's mother would look like. He explained that this is a bird equivalent of genes that are generated by gene detection.

This bird hybrid found in Pennsylvania has three species together.

Hybridization occurs commonly with Blue-winged and Golden-winged Warblers, but before Burket finds, hybridization is not recorded between these species and chestnut-side warblers.

"It's very rare," Toews said. "The female is a Golden-winged / Blue-winged Warbler hybrid, also known as Brewster's Warbler. Then he paired with a chestnut-side guy and successfully replicated."

Such hybridization is a rare occurrence, but it may occur more often in lesser winding populations because a smaller number of guys can choose.

Toews explained that hybridization in the declining population of golden poultry suggests that female species could best make a bad situation.

Toews also said that this suggests that warblers tend to be reproducibly compatible long after they independently developed great appearance differences.

"It tells us that warriors generally seem to be reproducible compatible with millions of years of independent evolution," says Toews Gizmodo.

"The things that really define them, their distinct colors and their tracks are likely to be mixing barriers and they do not mix because they can not but because they do not want it."

The results were published in the journal Biology Letters November 7th.
