Designated robin elimination of rare species were discovered by scientists

Rare species chernogorloy robin was discovered by scientists in the Qinling Mountains in north-central China. Fourteen species found recently doubled the total number of birds of this species since it was first opened 125 years ago. A group of Chinese and Swedish researchers has identified two areas for breeding robins distinct urge to males.

National wildlife reserves where birds were found, are also home of rare giant pandas and snub-nosed monkeys. Bird species Luscinia obscura (passerine) also known as chernogorlaya and chernogorlaya blue robin, were first discovered by researchers in 1886. These birds are singing, singing robins ochenzvonko, their singing is a variety of whistles, flute and chirping sounds are often inserted into the cries and voices of other birds. They share many characteristics with the European robin in size and shape, but the males are distinguished black throat and breast unusually red. Robins are usually prefer to stay far away from streams, wet places, youngish forests overgrown with bushes.

Until now, very little was known about this species, moreover, has never been able to find certain habitats females. "This kind of extremely secretive and it is very difficult to see in dense bamboo thickets, where he lives," - said Professor Per Alstrom (Per Alstrom), from the center of information on the types in Sweden, owned by the Swedish University of Agricultural Sciences in Uppsala.

Professor Ahlstrom and his colleagues were able to identify breeding birds on them a distinct singing. "It seems that females in this wild place approximately the same number as males but males are much easier to detect because they sing" - he said. Robins are known as extremely loud singers: one of the last they fall silent at night and very early songs meet the sunrise, so they are sometimes called robins.

Total research team has registered fourteen males in the national nature reserves and Channtsing Foping (seven birds each).

"Judging by the number of birds that we found this kind of, obviously, is not so rare as previously supposed, although he seems to be common in certain places," - said Professor Ahlstrom agency BBC Nature. "We spent three and a half weeks exploring different areas of the Qinling Mountains, but found this bird only in two places."

Selecting bird habitat has allowed the group of classifiers and birdwatchers hope to preserve the species. "Areas of excretion, which we found in the present study are well protected, as they are home to some rare species of mammals such as the giant panda and golden snub-nosed monkey" - said Professor Ahlstrom.

Scientists have made numerous recordings of singing birds in the hope that it will help them in the future identification of birds and provide a better understanding of the mysterious robins.
