Migration strategy, site fidelity and population size of the globally threatened Sociable Lapwing Vanellus gregarious

Population declines of the critically endangered Sociable Lapwing are probably due to high mortality along its migration routes or on its wintering grounds, both of which are very poorly known. We therefore undertook a long-term study of the species’ movements using satellite tagging, colour-ringing, targeted field surveys and a database of historical and recent sightings.
