Egg Covering In The Charadrii

Metadata Updated: December 11, 2019

Deliberate egg-covering in the Charadrii (waders) occurs in at least 13 species in four families (Jacanidae, Glareolidne, Charadriiclae and Thinocoridae). The habit is most widely developed in the genus Charadrius, of which at least four species cover their eggs. Egg-covering is done by kicking material over the eggs with the feet in most species, but in the Glareolidae and probably some other groups, only the bill is used. The primary function of egg-covering appears to be concealment, but the secondary function of thermoregulation appears to have become almost as important in a few species, especially as a device to insulate the eggs against exposure to the sun. It is not surprising that egg-covering is most highly evolved in tropical and subtropical regions where predator-pressure may be higher, and the danger of overheating by direct sun is greater, than elsewhere. The purpose of the present paper is to review the occurrence of egg-covering in the Charadrii in a attempt to analyze its functions against the background of wader ecology and of the occurrence and possible functions of egg-covering in other avian taxa.
