Breeding biology of the Kentish Plover Charadrius alexandrinus in the Sabkhat Al-Fasl Lagoons, Saudi Arabia (Aves: Charadriiformes)

The breeding biology of the Kentish Plover Charadrius alexandrinus was studied in the Sabkhat Al-Fasl Lagoons of Saudi Arabia, where ground temperatures may ex- ceed 55°C in summer. Although halophytic bushes are abundant, this species seems to prefer nesting at exposed sites. Biparental brood care was common: the females were absent in only three out of 24 families. Kentish Plovers attended their nests more than 80% over the full day and more than 90% of the time during day-time, and the number of change-overs increased during the hottest parts of the day which could be due to the possibility that a single parent cannot protect the eggs and itself from overheating.
