That, of course, is the sound of the Himalayan Forest Thrush. And that sound was a clue to field researchers that they might have a new species of bird on their hands, even though it was in the bush.

You know what I mean.

You see, the Himalayan Forest Thrush looks a great deal like another well-known bird

called the Alpine Thrush.

They're both found in northeastern India and nearby parts of China,

but the Alpine Thrush has a raspy song

compared with the more malefluous Himalayan forest thrush.

One of the researchers, Shashank Dalvi of India's National Center for Biological Sciences,

and the Wildlife Conservation Society,

likened the two different birds to Rod Stewart versus Adele. Further analysis,

including of the bird's DNA, confirmed that these song differences were indicative of these

birds indeed belonging to two separate species. The finding is in the journal Avian Research.

The discovery of a new bird species is relatively rare since the year

2000. Ornithologists have found five new species annually on average, mostly in South America. So this
