Abstract
The Pine Warbler (Setophaga pinus) inhabits eastern North America, where it breeds in the northern USA and Canada, and winters in southeastern USA. In Mexico, the species is considered an irregular winter migrant in the states of Nuevo Leon and Tamaulipas. We report the first record of the Pine Warbler for the state of Durango, in the protected area of the Cañon de Fernandez State Park, municipality of Lerdo. On 8 January 2023 at 11:42 h, a Pine Warbler was observed perched on a cypress tree (Taxodium huegelii), located on the banks of the Nazas River. The bird was on a branch approximately two meters above the ground. This record expands the species’ winter distribution in Mexico. Observations like this are essential for confirming movements of species in time and space during migration, and for documenting changes in the distribution of migratory species.
