Comparative foraging ecology of two broad-ranging migrants, grey plover Pluvialis Squatarola and whimbrel Numenius Phaeopus (Aves: Charadrii), in tropical and temperate latitudes of the Western Indian Ocean

Bibliography: leaves 186-205.A seasonal study of the nonbreeding foraging ecology of Grey Plovers and Whimbrels was undertaken at the Zwartkops estuary, South Africa, and additional data were collected from a variety of sites in tropical and south temperate latitudes during the premigratory period. The main objective of the study was to provide comparative data on shorebird foraging ecology in the southern hemisphere, in order to contribute to the general understanding of shorebird foraging behaviour and migration patterns
