Breeding success of the Stone Curlew Burhinus oedicnemus in Nag Valley (1999 2001), Kharan, Pakistan

Abstract

Variations in diferent breeding parameters in 2 adjacent populations of the Stone Curlew in Nag Valley were studied. A totalof 106 active nests were spotted, with an overall mean clutch size of 1.42 eggs per nest. Te nest and egg success of the Lope Valleypopulation was 0.50 and 0.42, respectively, while the nest and egg success of the Kereichi population was 0.60 and 0.45. Poaching ofeggs/chicks, habitat shrinkage, overgrazing, and fuel wood collection are thoughts to be the main factors afecting the breeding successof Stone Curlew in the area.
