Feeding

Habitat

Only nests in young jackpine woods of at least 80 acres in size with several small, grassy gaps. The Bahamas and Turks and Caicos in the winter.

Behavior

Yearlings and first-time breeders search for new breeding grounds, although ringed males have been recorded returning to the same nesting site year after year; one male ringed at CFB Petawawa in Ontario in 2006 returned for six years. This individual lived to be nine years old, but the species is known to have significantly lower lifespans in general; males live to be four years old on average, while females live to be 2.5 years old on average.
