Calidris bairdii

Calidris bairdii, commonly known as Baird's sandpiper, is a small migratory bird found in North and South America. It has a slender body, short bill, and plumage that is mostly mottled brown and white, providing good camouflage in its habitat. During migration, it travels between nesting grounds in northern regions and wintering areas in Central and South America. Baird's sandpiper primarily feeds on insects and small invertebrates, foraging along shorelines, mudflats, and beaches. Its migratory behavior and habitat preferences make it an important species for monitoring environmental health, especially in wetland and coastal ecosystems.
