In 1999 she won the National Environmental Prize in the category of Environmental Education, awarded by Comisión Nacional del Medio Ambiente (CONAMA).

Vanellus gregarius

Vanellus gregarius (Pallas, 1771)

Some facts about this bird:

Head and body length: 27–30 cm.

Wingspan: 70–76 cm.

Weigth: 150–260 grams.

Habitat: Breeds in steppes. Prefers sandy short grass plains and meadows during non-breeding season.

Distribution: Breeds in northern and central Kazakhstan and south-central Russia.

Diet: Chiefly feeds on insects.

Surviving number: Estimated at 11,000.

Conservation status: Critically Endangered (IUCN 3.1 [2024-2])

First described: By the German zoologist and botanist Peter Simon Pallas in 1771 as Charadrius gregarius.


Vanellus gregarius is a well-traveled tourist. This bird's flight routes take it from the breeding grounds in the steppes of Kazakhstan and Russia to locations throughout the Middle East. It has even been found as far south as Sudan and as far east as India. The species is monogamous. A single clutch of usually four eggs per season are laid in an unlined depression on the ground. The eggs are then incubated for about 25 days. Illegal hunting and habitat loss made the Sociable Lapwing population decline by 70% in the 20th century.
