A distinctive whistle pave the way for the discovery of new bird species


A new bird species Sichuan Bush Warbler was finally found in the central China’s mountain terrain, which has a tendency to hide in the grassy vegetation. The elusive bird is confirmed as a new species and found out by its distinctive song.Sichuan-Bush-Warbler

The new bird is named as Locustella chengi, and made a debut in a research paper, which is published in Avian Research. The elusive bird is named after the late Chinese ornithologist Cheng Tso-hsin and it looks similar to other species, Russet Bush Warbler. Both the species live more or less in the same place and the new species sounds different from the other one, which made it to get distinguish from the previous one.

Pamela Rasmussen, a biologist at Michigan State University, who co-authored in the research paper said in a statement as,

“Its distinctive song … consists of a low-pitched drawn-out buzz, followed by a shorter click, repeated in series,”

The sound has been recorded, and stored in the Avian Vocalizations Center, that can be heard from here. The new species is very hard to find and but, can be seen appearing pretty common over the region. The two species are distinguished by only slight differences and it is “typically greyer (less russet) above and on the breast-sides and flanks,” The differences that researchers noted doesn’t hold longer, and it will be very hard find the differences all the time.

Moreover, both the Bush Warblers are living together and according to the observations, both the male of those two species are partly overlapping the territories of each other’s. Once the researchers found that, male species of Sichuan Bush Warbler were chasing the male species of Russet Bush Warbler for overlapping their territories.

The research paper indicates us that, it seems that the researchers aren’t too much surprised by the discovery. Researchers mentioned that, it has been just a “long history of taxonomic confusion.
