"Least-known Bird" Has Been Found

Researchers at the Wildlife Conservation Society (WCS) have found the breeding area of the elusive large-billed reed warbler. That's a big deal, because according to BirdLife International, the species is the world's "least-known bird."

The distinction may sound ominous, but it's also impressive considering the amount of time that has gone between warbler sightings. After the first specimen was discovered in India in 1867, it took well over a hundred years to find the second -- another single bird found in Thailand in 2006.
