The aptly named Mexican Parrotlet is the northernmost Forpus and endemic to northwest Mexico. They are fairly common in riparian woods and semideciduous to deciduous woodlands and plantations. As with other parrotlets, they are usually found in pairs or flocks, and are often first detected by their excited screeching and twittering calls. They may be very difficult to find when perched given their small size, and leaf-like appearance. Flight is fast; usually in tight formations. The tail is short and square.
