Pluvianidae – Egyptian Plover

Egyptian Plover Pluvianus aegyptius ©Nigel Blake Website

The Pluvianidae has Egyptian plover, also known as the crocodile bird, as the sole member of its own monotypic family. It is a wader, the only member of the genus Pluvianus and was formerly placed in the pratincole and courser family, Glareolidae. The species is one of several plovers doubtfully associated with the ‘trochilus’ bird mentioned in a supposed cleaning symbiosis with the Nile crocodile.

It is a striking and unmistakable species. The 19cm to 21cm long adult has a black crown, back, eye-mask and breast band. The rest of the head is white. The remaining upper plumage is blue-grey, and the underparts are orange. The longish legs are blue-grey.

In flight, it is even more spectacular, with the black crown and back contrasting with the grey of the upper parts and wings. The flight feathers are brilliant white crossed by a black bar. From below, the flying bird is entirely white, apart from the orange belly and black wing bar. After landing, members of a pair greet each other by raising their wings in an elaborate ceremony that shows off the black and white markings. The sexes are similar, but juveniles are duller and the black marking are intermixed with brown. This usually very tame bird is found in pairs or small groups near water. It feeds by pecking for insects. The call is a high-pitched krrr-krrr-krrr.

The bird is sometimes referred to as the crocodile bird for its alleged symbiotic relationship with crocodiles. According to Herodotus, the crocodiles lie on the shore with their mouths open and a bird called trochilus flies into the crocodiles’ mouths so as to feed on decaying meat lodged between the crocodiles’ teeth. The identification of the trochilus with any particular plover is doubtful, as is the cleaning symbiosis itself; no known photographic evidence exists, and the written accounts are considered suspect.
