Origin, geographical range and distribution
The Caspian plover species are distributed in southwest Asia and Africa. The breeding populations are distributed in Kazakhstan, northwest China, Uzbekistan, Kyrgyzstan, Turkmenistan and north Iran.The wintering populations occur in south and east Africa. Vagrants have been reported from United Kingdom, Turkey, Seychelles, Russia, Romania, Maldives, India, Sri Lanka and Mali.
In India, vagrant Caspian plover "sightings have been reported from Delhi (Vyas 1996), Gujarat (Robson 2007; Sørensen & Tiwari 2009), Goa (Lainer 2004), Maharashtra (Prasad 2006), Pondicherry (Balachandran 1994), and Tamilnadu (Kazmierczak et al. 1993; Robson 1996)".
The Important Bird and Biodiversity Areas (IBA) of these Caspian plover species in Kazakhstan are, Zhusandala, Sagyz, Donyz-Tau cliff faces, Caspian Sea shore between Volga and Ural River Deltas and Arys-Karaktau State Reserved Zone.
The IBA of these species in Tanzania are, Singida lakes, Lake Manyara, Serengeti National Park, Longido Game Controlled Area and Ngorongoro Conservation Area. The IBA in Uzbekistan is Sudochye Lake.
Ecosystem and habitat
The Caspian plover species do not normally occur in forests. They normally occur in altitudes between 0 to 800 meters.The artificial ecosystems and habitats of these species include agricultural lands, pasturelands, salt production facilities and aquaculture farms.
The natural ecosystems and habitats of these species include temperate grasslands, tropical and subtropical grasslands, hot deserts, coastal sand dunes, shorelines and coastal and freshwater wetlands.
Diet and feeding behavior
The diet of this Caspian plover species consists mainly of insects. Adult and larval insects such as beetles, ants, termites, grasshoppers, bugs, caterpillars and flies are their primary food. They feed on the ground as well as in very shallow waters.Reproduction and breeding habits
The breeding season of these Caspian plover species is from April to June in most of their breeding range. These species are monogamous and territorial.The nesting sites include temperate grasslands and desert steppe near water. The nest is a shallow scrape on open ground or amongst low vegetation (del Hoyo et al. 1996).
Migration and movement patterns
These Caspian plover species are fully migratory birds (del Hoyo et al. 1996). The breeding populations occur in Kazakhstan, Uzbekistan, Kyrgyzstan, Turkmenistan and north Iran.These populations migrate between August and October for wintering in Africa. The return migration to the breeding grounds occurs between March and early-May, with stop-overs in Arabian Peninsula and the Red Sea area.
