The snake Pseustes poecilonotus (in Trinidad and Tobago known as dos cocorite, in Brazil as papa-ovo and, in English, as the puffing or bird snake) is in the family Colubridae, is non-venomous and is found from Mexico through Central America to northern and central South America and Trinidad and Tobago. It apparently eats any terrestrial vertebrate small enough to handle and is well known as a predator of bird eggs (hence some of the common names). Its color pattern is relatively consistent, darker dorsally and lighter, usually yellow, ventrally. Young snakes can be more colorful than adults and so may mistakenly be thought to be a different species. However, when handled, their behavior is similar and they will readily bite.
