Wonderful successful comeback of the Kirtland warbler, thanks to conservation efforts. Patti gracis for the post.

This is why the bird is endangered
:arrow: Kirtland's warblers have been on the endangered species list since 1967. Their population hit a low of 201 males in 1971, dropping from 432 singing males in 1951.

But their numbers now are among the highest recorded, 1,486 males in 2006.
Scientists and bird lovers are celebrating a milestone in the recovery of a highly endangered songbird as an active Kirtland’s warbler nest was discovered on private property in Wisconsin, the U.S. Fish and Wildlife Service announced today.
The tiny Kirtland’s warbler, whose distinctive mating call can be heard up to a quarter of a mile away, lives primarily in jack pine forests in the northern lower peninsula of Michigan. However, the species has been seen in recent years in other areas, including Wisconsin, Ontario and the Upper Peninsula of Michigan.
The nest was discovered by a birder who found the first Kirtland’s warblers in the area several weeks ago. Recognizing the significance of the discovery, this private citizen came forward and has been assisting the Fish and Wildlife Service and Wisconsin Department of Natural Resources in documenting the presence of Kirtland’s warblers in the state.
“This development is a testament to decades of cooperative conservation among the states of Michigan and Wisconsin, private landowners, and organizations such as the Audubon Society,” said Robyn Thorson, regional director for the U.S. Fish and Wildlife Service’s Midwest Region. “This discovery proves that by working together, recovery and range expansion for an endangered bird are not only possible, but are happening as we speak.”
The nest was discovered on land in central Wisconsin owned by the Plum Creek Timber Company.
