Ecosystem and habitat
These sociable lapwing species do not normally occur in forest. They normally occur in altitudes from 0 to 300 meters. The artificial ecosystems of these species include rural gardens, cultivated lands and ploughed and stubble fields.The natural ecosystems and habitats of these sociable lapwing species include dry wastelands, temperate deserts, burnt steppe, savannah, tropical and subtropical dry grasslands, temperate grasslands, steppes, brackish or alkaline lakes and wetlands.
Diet and feeding behavior
The diet of sociable lapwing consists mainly of insects. Insects, caterpillars, beetles, grasshoppers, cicadas, spiders, scorpions and crickets are their primary food.These lapwings also feed on seeds, grains, leaves and flowers. These species forage on the ground, picking insects and other small prey. Ploughed fields and grasslands are their favorite feeding grounds.
Reproduction and breeding habits
The breeding season of the sociable lapwing species is from April to July in most of their breeding range. These birds are monogamous and breed in small colonies.The nesting sites of sociable lapwing are usually located near water on bare saline plains or on short vegetation. The nest is a scrape, which may be bare or lined with twigs, grass and pebbles.
The lapwing clutch contains three to four pale buff, ovoid eggs with dark olive brown mottling. The breeding pair take turns to incubate the eggs. The chicks hatch out after 25 days. The parents brood the chicks. The chicks are precocial and are able feed themselves.

These sociable lapwing species are partially migratory birds. The breeding populations in the northern and central Kazakhstan and south-central Russia disperse and migrate south during August and September.The wintering populations of sociable lapwings in Sudan, Pakistan, northwest India, Saudi Arabia, Oman and UAE make the return migration to the breeding grounds during March and April.
