Ibisbill

Ibidorhyncha struthersii

The Ibisbill (Ibidorhyncha struthersii) is a medium-sized shorebird of remarkable appearance and a truly unique evolutionary lineage. Measuring 38-41 cm in length with a wingspan of 70-80 cm and weighing 270-320g, its most striking feature is a long, decurved, crimson-red bill, strikingly contrasting with its otherwise cryptically colored body. Adults boast a slate-grey body, white belly, a black face, and a distinct black band across the breast, while their legs are also bright red. This com...

Habitat

Found exclusively along the stony banks and braided channels of fast-flowing, high-altitude mountain rivers and glacial meltwater streams, typically at elevations between 1,700 and 4,400 meters.

Diet

Primarily carnivorous, feeding on a specialized diet of aquatic invertebrates, such as insect larvae (caddisflies, stoneflies, mayflies) and sometimes small crustaceans or tiny fish, expertly extracted from under riverbed stones.

Its foraging strategy is highly specialized: it wades through shallow, swift-moving water, using its unique long, downcurved bill to probe under and around submerged stones...

Range

The Ibisbill is endemic to the high-altitude mountain ranges of Central Asia and the Himalayas, with its range extending across a vast, yet fragmented, distribution. Its primary breeding grounds span from the Tien Shan and Alay Mountains of Kazakhstan, Kyrgyzstan, Tajikistan, and Uzbekistan, east...
