Highlight
The Kirtland’s warbler is a songbird that nests in young jack pine stands. Until 1995, Kirtland’s warblers had only been known to nest in the northern part of Michigan’s Lower Peninsula. Today, they also nest in the Upper Peninsula and have been observed in Wisconsin and Canada since 2007. They migrate from their nesting grounds to the southeastern coast of the United States on their way to wintering grounds in the Bahamas.
Wildlife Services wildlife biologists are partnering with the United States Fish and Wildlife Service and the Wisconsin Department of Natural Resources to trap brown-headed cowbirds from Kirtland’s Warbler nesting sites. Brown-headed cowbirds have significantly impacted Kirkland’s warbler nesting success by invading nests, replacing warbler eggs with cowbird eggs, and leaving Kirkland’s to raise cowbirds. The trapping program has been a key component to at least 19 Kirkland's successfully leaving the nest this year.
