Breeding

The pallid harrier breeding season is during May and June. The nest is built on the ground and four to six eggs are seen in the nest.

Distribution

The pallid harrier is distributed in Europe, Asia, Indian Subcontinent and Africa. Breeding populations are found in southern parts of eastern Europe and central Asia including Asiatic Russia, Kazakhstan, north-west China Azerbaijan, Romania, Turkey and Ukraine. They migrate and winter in tropical African countries including Sudan, Ethiopia, Somalia, Kenya, Uganda, Namibia, Botswana, Swaziland and South Africa. They also migrate to the Middle East and Indian subcontinent.

The pallid harrier is completely migratory, the birds in the northern regions migrating southwards for wintering.

Status and conservation

The pallid harrier global population is estimated at 9,000 to 15,000 pairs. The habitat loss due the destruction and degradation of steppe grasslands and their conversion to agricultural lands, burning of vegetation, intensive grazing of pastures and reduced availability of prey are the main threats to the survival of these bird species.

The IUCN (International Union for Conservation of Nature) has categorized and evaluated these harrier species and has listed them as "Near Threatened".
