Scientists have confirmed that a frog found living in New York City wetlands is a new species.
Jeremy Feinberg, of Rutgers University in New Jersey, who led the study, first reported the discoverywhen he heard their "very odd" chorusing call.
Teaming up with genetics experts to confirm the finding, Mr Feinberg has now published the discovery in the journal Plos One.



It is the first new frog species found in the region for nearly 30 years.
Mr Feinberg told BBC News he knew he might be on to something when he heard a group of them calling in chorus at a wetland study site on Staten Island.
"Frogs have very stereotyped calls within a species, so I knew this was different," the ecologist told BBC News.
"But it took me two years to find someone to partner with me on the genetics side."
He believes the frog, named Rana kauffeldi - a leopard frog - probably once inhabited Manhattan, so it had been seen before. But it was assumed to belong to a similar-looking, previously known species of leopard frog (so named because of its spots) found in the same area.
Mr Feinberg's familiarity with the known species meant that its call finally gave it away.
