With nearly 800 species, Oaxaca has the biggest bird list of any Mexican state, and almost 100 of these are regional endemics. With impressive ruins, a bustling capital city rich in commerce and architecture, vibrant native culture, and some of the world’s most beautiful beaches, Oaxaca is hard to beat for a Mexican birding trip. A large number of North American breeding species winter in this area, and we can expect to see numerous migrant warblers, vireos, flycatchers, and other species as well. The optional extension takes in some of the best birding areas of the neighboring state of Chiapas, and targets some truly stunning species such as Rose-bellied Bunting and Pink-headed Warbler.
