The Palm Warbler breeds from southeastern Yukon and northeastern British Columbia east to Newfoundland and in scattered areas along the northern regions of the states from Minnesota to Maine. The species winters on the Atlantic and Gulf coasts from Delaware to Texas, the West Indies, parts of the Central American Gulf Coast and the Pacific Coast from British Columbia to Northern Mexico. The Palm Warbler is an uncommon migrant across Montana with fewer than four observations reported in a typical year (Wilson 2013, MTNHP 2019).
