Officials celebrate recovery of tiny Kirtland’s warbler
2:52 p.m. EDT March 31, 2016
Grayling — Officials say a long battle to save a Michigan songbird from extinction has succeeded.
A team that has supported recovery of the Kirtland’s warbler for decades held a final meeting this week in Grayling. It included officials with state and federal agencies, researchers and private groups.
Deputy assistant secretary Michael Bean of the U.S. Department of Interior says a recommendation could come as early as next year to remove the warbler from the endangered species list. A 2015 census estimated the population at 2,366 breeding pairs. That’s up from a low of 167 pairs in 1974.
