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 discovery when 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.
