Order: Charadriiformes
Family: Scolopacidae
The Lesser Yellowlegs is a slender, medium-sized shorebird recognized by its long, vivid yellow legs and straight, thin bill. In Patagonia, it is a regular migrant visitor, often seen in shallow wetlands, mudflats, and flooded fields during the austral summer. Its plumage is mostly gray-brown above with white below, and it is known for its active foraging style, frequently wading through water in search of food. The species is highly vocal, especially when alarmed, emitting a series of sharp, ringing calls. Lesser Yellowlegs are often found singly or in small groups, sometimes mixing with other waders. Their presence in Patagonia highlights the region’s importance as a stopover and wintering ground for migratory shorebirds.
Habitat
Prefers shallow freshwater and brackish wetlands, mudflats, flooded fields, and lake shores across Patagonian lowlands.
Foraging
Feeds by wading in shallow water, picking insects, small crustaceans, and other invertebrates from the surface or just below.
