This warbler’s northern breeding limit extends from northeastern British Columbia east to Newfoundland. The southern limit extends from central Minnesota east to New England and south through the Appalachian Mts. to central Alabama; small, isolated populations exist south and west of the main range. The poorly differentiated D. v. waynei breeds on the Atlantic coast, from southern Virginia to southern South Carolina. The species winters primarily in the northern West Indies and from extreme southern Texas south along the Atlantic slope of Middle America to central Panama. Smaller numbers winter on the Pacific slope of Middle America from Nayarit southward. The species winters rarely in southern Florida, the Lesser Antilles, and from eastern Panama to northern South America. It winters casually elsewhere in the United States, typically in the south. Oregon’s two December records, in Eugene 7 December 2001 and in Klamath Falls 9–22 December 2005 (NAB 60:278, 318), may have involved late fall vagrants. This is a very rare but regular migrant through the West (including the Baja California Peninsula). Extralimital records extend to southeastern Alaska, the western Northwest Territories, southwestern British Columbia, Nunavut (Richards et al. 2002), the Islas Revillagigedo, Clipperton Atoll, Greenland, Iceland and surrounding waters, and Germany.

California’s first Black-throated Green Warbler, a first-spring female, was collected on 29 May 1911 on Southeast Farallon Island (Dawson 1911, CAS 18080). The state total stands at approximately 300 records, with roughly 80% in fall (3 September–8 December, peaking mid October to mid November) and 10% each in spring (9 May–5 July) and winter; most wintering birds are found along the southern coast. Birds have returned for multiple winters, including a male that spent eight straight in National City, San Diego County (NAB 58:283).
