Populations of rare songbird found in surprising new habitat

30 octubre 2014

With only 90,000 breeding individuals sparsely distributed across 15 US states, the Swainson’s warbler is a species of high conservation concern that, for decades, has left conservationists with little confidence that its populations would ever be fully secure. New research reveals that populations of Swainson’s warbler are increasing in a surprising new habitat found mostly on private lands — pine plantations on nearly 16 million hectares on the coastal plain from eastern Texas to southeastern Virginia.
