They placed stuffed females of different finch species on branches to see which males would respond. In fact, Dr. Lovette said, about 10 percent of the worlds 10,000 bird species are known to have bred with another species at least once, either in the wild or in captivity. $("#2Dcheck").text("(Correct) "); //This is text for screen readers "Many birds occasionally mate with members of other bird species, producing hybrid offspring," said Irby J.

The desert finch, also called the Lichtensteins desert finch, is a big brown finch that lives in Eurasia. She graduated from the University of Glasgow in 1987 with a degree in veterinary medicine and surgery. That reproductive separation between geographically overlapping but biologically compatible species -- technically known as allopatric speciation -- is considered an important phase in species divergence. $("#7Acheck").text("(Correct) "); //This is text for screen readers D.

Differences in just 82 DNA letters, out of a total of about 1.2 billion, appear to separate the two groups. Natural selection favors traits, such as beak depth, that provide a survival or reproductive advantage in a particular environment. Its found in coastal areas in South Africa, in shrubs and gardens.
