Vireo flavoviridis (Yellow-green vireo)
The yellow-green vireo (Vireo flavoviridis) is a small passerine bird. It breeds from southern Texas (occasionally the Rio Grande Valley) in the United States and the western and eastern mountain ranges of northern Mexico (the Sierra Madre Occidental and Sierra Madre Oriental—also the Cordillera Neovolcanica) south to central Panama. It is migratory, wintering in the northern and eastern Andes and the western Amazon Basin.
