The Egyptian plover (Pluvianus aegyptius), also known as the crocodile bird, is a wader, the only member of the genus Pluvianus. Formerly placed in the pratincole and courser family, Glareolidae, it is now regarded as the sole member of its own monotypic family Pluvianidae.

The species is one of several plovers doubtfully associated with the “trochilus” bird mentioned in a supposed cleaning symbiosis with the Nile crocodile.(source)
