Bird hybrids found in the backyard of Pennsylvania are one of three species, DNA tests revealed.

Earlier this year, yellow, black and white birds found in Pennsylvania's backyard turned out to be three hybrids.

Bird observer Royell Burket discovered the physical characteristics of blue-winged mules and golden-winged mules when they saw male birds in the borough of Roaring Spring in May. Huffington Post Reported. While the birds sang like a third species, chestnut-sided wimps.

Burket contacted Fuller Evolutionary Biology Lab at Cornell after taking pictures and videos of birds. The lab was fortunate to meet with email and researcher David Toews.

They took a blood sample and measured it again when a bird was found. DNA analysis revealed that Burket was right about the algae.

It is one of three species. The mother of the bird was a hybrid between a blue winged mule and a golden winged mule, and his father cried chestnut.

In a press release by Cornell Lab of Ornithology, Toews explained that he looked at genes with various polar colors to reproduce what birds would have seen. He explained that this is an algae equivalent to the facial composition of a detective created with the help of a gene.

This bird hybrid found in Pennsylvania is one of three species.

Hybridization generally occurs between Blue-winged and Golden-winged Warblers, but no hybridization was recorded between this species and the Chestnut-sided warblers until Burket was discovered.

"It is very rare," Toews said. "Women are golden – wings / hybrid winged hybrid – also called Bruce Warbler, who has successfully reproduced with the Chestnut-sided Warbler."

This type of crossbreeding is rare, but the fewer colleagues you can choose from, the less dirty the population, the more often it can occur.

Toews suggests that hybrids can overcome bad conditions for females as the population of Golden-winged warblers decreases.

Toews also suggested that warblers were generally not cloned as long as they evolved their apparent major differences independently, and were generally clonally compatible.

"It seems that warriors are reproducibly compatible with millions of years of independent evolution," Toews said. Gizmo.

"Indeed, defining them, their distinctive colors and songs are highly likely to break through the barriers and do not cross because they can not.

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