A 'Trochilus' bird, perhaps a Sandpiper or Plover, Spur-winged Plover eats leeches from from the teeth of a Nile Crocodile, in a classic supposed example of cleaning symbiosis.
- Egyptian Plover (Pluvianus aegyptius). Africa's Spur-winged Plover Vanellus spinosus is a lapwing and has black head with bold white triangle opening towards neck. P. aegypticus is a courser with a black head with two thin white stripes as here. The behaviour is apparently real, but not well documented. Dysmorodrepanis 21:35, 4 April 2008 (UTC)
- Whatever the portrayed bird is meant to be, it is neither a Spur-winged plover (for instance black belly) nor an Egyptian plover (for instance black hindneck). The African bird it most resembles is the White-crowned/headed plover/lapwing (Vanellus albiceps). I guess the illustrator/author was not too familiar with African birds.
- I wonder. The behaviour has been recorded among Sandpipers in Egypt, and the bird drawn is not unlike the Common Sandpiper (Actitis hypoleucos) (which overwinters in Egypt), so perhaps the artist used that as the model. Chiswick Chap (talk) 11:01, 17 February 2012 (UTC)
- A footnote: there is little evidence for cleaning symbiosis between any bird and the Nile Crocodile, but what there is suggests that Herodotus and Scherren most likely heard about sandpipers; and Scherren clearly picked a sandpiper as his model for this illustration.
