Breeding Range (Green)
Kirtland's Warblers primarily breed in the Lower Peninsula of Michigan, with more recent and growing populations in Michigan's Upper Peninsula, Wisconsin, and Ontario. Migration Range (Yellow) After spending the winter in The Bahamas, Kirtland's Warblers migrate west to the Florida and Georgia coasts and continue northwards back to the breeding grounds. In the fall, Kirtland's Warblers move east into Ontario, western New York, or Pennsylvania. They then fly straight south, beginning flights over the ocean from the Carolina coasts before reaching their wintering grounds. On average, their journey takes 16 to 18 days to complete, with some birds traveling the 1700 miles in just 10 days! Wintering Range (Blue) Kirtland's Warblers have historically wintered in the Bahamian Archipelago (with a few winter sightings on the coast of Florida, the Dominican Republic, coastal Mexico, and Bermuda). Recent investigations have also confirmed their presence in Cuba. Header Photo: Katie Koch |
