Biomes
Montane wetlands, high-altitude lakes, rivers, coastal estuaries, harbors, agricultural fields, and urban areas.
Geographic range
Breeds in high-altitude regions of Central Asia (Tibetan Plateau, Himalayas, and surrounding mountain ranges). Winters across South Asia (India, Bangladesh, Pakistan, Nepal, Sri Lanka) and Southeast Asia (Myanmar, Thailand, Vietnam, Cambodia).
Preferred environments
Freshwater and brackish lakes, large rivers, reservoirs, coastal mudflats, estuaries, and irrigated agricultural lands during winter. Breeding habitats include remote, often inaccessible, high-altitude lakes and marshes with sparse vegetation.
Elevation range
Breeds at elevations typically between 2,000 and 5,000 meters (6,500-16,400 feet). Winters at sea level up to lower elevations.
Where to look
High-altitude Lakes (Breeding)
During the breeding season (May-July), search for colonies on islands or remote shores of large lakes and marshes on the Tibetan Plateau and Himalayan regions.
Coastal Estuaries and Harbors (Wintering)
In winter (September-April), check coastal areas, especially estuaries, deltas, and harbors in India, Bangladesh, and Southeast Asia.
Inland Lakes and Rivers (Wintering)
Look for them on large freshwater lakes, reservoirs, and major river systems throughout their wintering range.
Agricultural Fields
They often forage in irrigated agricultural fields, especially rice paddies, during winter.
Field tips
- Scan large flocks. Brown-headed Gulls are gregarious; look for their distinctive head and wing patterns within mixed flocks of gulls and terns.
- Observe foraging behavior. Watch for their characteristic surface-picking, wading, or shallow plunge-diving behavior in water bodies, or hawking insects in flight.
- Listen for calls. Familiarize yourself with their nasal 'kwaaa' calls, especially around breeding colonies or feeding aggregations.
- Consider seasonality. Remember the dramatic plumage changes between breeding and non-breeding seasons to avoid misidentification.
Migration
Long-distance migrant. Breeds in Central Asia and undertakes southward migration to South and Southeast Asia for the non-breeding season. Migration routes can cover thousands of kilometers, often following major river valleys and mountain passes.
