What is the general northern boundary the breeding range of the White-Eyed Vireo can reach along the Atlantic states?

Answer

Southern New England in some years.

During the breeding season, the core distribution is centered in the southeastern United States. However, the range extends northward along the Atlantic coast, with documentation showing that in certain years, the presence of breeding individuals can stretch as far north as the southern region of New England before the seasonal distribution shifts south again.
