Deforestation threatens newly identified bird in Brazil

from Scientific American

Discovering a new species isn't always as easy as saying "Look, there's a new species!" In the case of a rare bird recently identified in Brazil, it took about 20 years for scientists to gather enough evidence to classify it as a new species. The journey began in the early 1990s when scientists found an isolated population of songbirds in the heavily logged mountains of Bahia, Brazil. At the time researchers labeled the small (12 centimeters in length) birds in this location as a previously known, widespread species called the mouse-colored tapaculo (Scytalopus speluncae). A second, equally isolated population was discovered nearby in 1999. Three more sites in the mountains of Bahia followed, all heavily degraded by logging and deforestation. more
