 Go to Audubon's Priority Birds page for this species: http://www.audubon.org/field-guide/bird/black-throated-blue-warbler

 Learn how climate change could affect this bird's range: "In the broadest and most detailed study of its kind, Audubon scientists have used hundreds of thousands of citizen-science observations and sophisticated climate models to predict how birds in the U.S. and Canada will react to climate change."

More on this bird in the Wisconsin All-Bird Plan:  http://www.wisconsinbirds.org/plan/species/btbw.htm

"Loss or fragmentation of large blocks of older, structurally complex forests may negatively impact this species. Overbrowsing by deer may suppress populations locally by reducing the shrub layer available for nesting (WDNR 2005). Loss of habitat on the wintering grounds in the West Indies also is suggested as a possible limiting factor (Holmes 1994)."
