Rare crow. Thought Extinct, Is rediscovered

A critically endangered Indonesian crow — long feared extinct — has been rediscovered in its native habitat, scientists announced today.

The all-black Banggai Crow (Corvus unicolor), known to science only by two specimens described in 1900, was found again by Indonesian biologists on Peleng Island, off the east coast of Sulawesi, Indonesia, in 2007. Pamela Rasmussen, a Michigan State University zoologist verified the finding.

Rasmussen studied the two century-old specimens, housed at the American Museum of Natural History in New York, and compared them to the new specimens to make sure they were not just members of a different all-black subspecies of crow, the more common Slender-billed Crow (Corvus enca).

"The morphometric analysis I did shows that all four unicolor specimens are very similar to each other, and distinctly different from enca specimens. We also showed that the two taxa differ in eye color — an important feature in Corvus," Rasmussen said. "Not only did this confirm the identity of the new specimens but also the specific distinctness of Corvus unicolor, which has long been in doubt."
