Kirtland's Warbler

October is a time of falling leaves, eager trick-or-treaters, and the southward migration of the exceptionally rare Kirtland's warbler.

The Kirtland's warbler is found almost exclusively in the jack pine forest of northern Michigan. To counteract the devastating impact of habitat loss on the bird's population, the Michigan Department of Natural Resources initiated the Kirtland's Warbler Management Plan in 1981.

By the time the song birds return to their Michigan breeding grounds next year, the Kirtland’s warbler may no longer be listed as an endangered species.

The Kirtland’s warbler is a songbird with an enviable travel schedule. The birds spend the winter in the Bahamas, and in the spring, they come home to the Great Lakes region – mostly to Michigan’s northern Lower Peninsula.

The warbler has been on the endangered species list for 40 years. But it’s been doing well lately. Federal officials say the birds have met their recovery goal.

But it’ll take a lot of work to manage the birds even after they’re taken off the endangered species list.

Kirtland's warblers are moving south to their winter home in the Bahamas (lucky devils), but before they left Michigan, researchers counted 1,805 singing males.

That's less than the high in 2009 (1,826 singing males) but more than last year's count (1,773 singing males), and researchers say it's a sign of a healthy population.
