The genome is from a specimen in a private collection in Spain

A genetic study of the U.S.'s only native parrot is displayed, to confirm their extinction, the people were alone.

the scientists sequenced the genome of a Carolina parakeet stuffed instead of in a private collection.

The colorful Bird -DNA showed no signs of inbreeding characteristic of animals which have been in decline for many years.

Instead, its genetic sequence population suggests the lively, to the enlargement of the European settlers.

The Parrots then disappeared abruptly with The Last of the prisoners specimen dying in the Cincinnati Zoo on 21. February, 1918. The Bird was once found from New England to The East , Colorado in The West .

The Bird had green plumage with a yellow head, and measured about 13ins (33cm) long. They lived in old forests along rivers and in swamps.

"a Lot of Endangered Species have been sequenced, and what seems to be a pattern is that when populations are small and declining for a long time, this some of the signals that can be detected in their genomes," co-author Carles Lalueza-Fox of the University of Barcelona, explains.

"Even if you have a single sample, such as here, we have a genome from The Father and genetic from The Mother ; two copies of each chromosome. If the population was low, for thousands of years, these two specimens are very similar to each other over long distances and sometimes they will be identical. "

If a population is large, Dr. Lalueza-Fox, said that the two chromosome copies, is genetically different. In fact, this is what The Team saw in the Carolina 's exactly parakeet (Conuropsis carolinensis).

"The implication is that this Bird was the subject of a very long population decline for thousands of years, it was something very quickly," the University of Barcelona geneticist explains.

Dr. Lalueza-Fox, that the extinct Bird 's closest living relatives, The Sun parakeet (Aratinga solstitialis), has the in South America , much less genetic variation.

The exact mechanism of the Carolina parakeet to extinction remains shrouded in mystery, however.

deforestation, along with hunting and trapping, both need to have played the roles in his downfall. Disease and competition with non-native honey bees can be factors also.

The Birds gathered in large, noisy crowds, and were sociable in their behaviour. Contemporary observers noted that they would return to the sites of dead or dying birds that the wholesale slaughter of herds even easier for the hunter.

The American naturalist John James Audubon had commented on The Birds ' declining numbers in the year 1832. The Birds were gone, The Wild by the early 20Th Century . Century .

A Carolina parakeet, The researchers also found evidence for a genetic adaptation to the Bird 's-toxic diet is depicted in an engraving from the late 18Th Century ,

. The Carolina parakeet had a penchant for eating cockleburs, a rough Flowering Plant , contains a powerful toxin called carboxy-atractyloside.

The Poison accumulated in the Bird fabric, and there are records of cats that were eating Carolina parakeets is found dead.

The researchers discovered genetic variations in two well-known proteins inter-a diet interact with carboxy-atractyloside could be based on, tables to adapt to The Poison .

The Birds are a target for de-extinction, the scientific discipline that tries to give you the lost species back from The Dead .

One approach might be, The Sun conure, and use genome-to change edit to view the its DNA code, like its extinct relatives. But despite the similarities between the two species, this is far from easy.

hundreds of specimens of the extinct Bird will remain in museums

"If we compare the two genomes, we can easily see, there are a list of several hundred protein-coding genes, the changes seem to be functionally important," Prof Lalueza-Fox, the Bbc News said.

"It is an enormous task. But even if we wanted to do, as far as I know, no one was able to clone a Bird . no one knows How To change something before you become an egg.

"If you want something, the genome highlights the huge difficulties behind the de-extinction ideas. I'm not saying it's impossible, but it is incredibly difficult. "

The Last prisoners of the Carolina parakeet and The Last Passenger Pigeon that died, died in the same cage, four years earlier. The Decline of the two birds parallel.

The genome-sequencing project, a journalist began as a copy found in a private collection in Espinelves, North-East Spain. The stuffed Bird had been acquired by an ancestor of the current owners.
