Calidris ruficollis
The Red-necked Stint, *Calidris ruficollis*, is a diminutive and highly migratory shorebird, known for its compact build and distinctive breeding plumage. Measuring approximately 13-16 cm (5-6.3 inches) in length with a wingspan of 28-31 cm (11-12.2 inches) and weighing 20-35 grams, it is one of the smallest species within the diverse sandpiper family.

This species primarily breeds on the high Arctic tundra, particularly in damp, mossy areas near pools and low-lying vegetation. During migration and winter, they inhabit coastal mudflats, sandy beaches, estuaries, and brackish lagoons, typically at sea level.
