Dr. Bondar will soon be starting her fall and winter field work, some of which involves following the Red Knot (Calidris canutus), one of the signature birds of the Space for Birds Project, in its winter habitat.
The endangered Canadian subspecies of the Red Knot, Calidris canutus rufa, has come to attention in recent years given its 70% decline in abundance in a span of 15 years as of 2016.1
The rufa Red Knot is part of the sandpiper family, and has typical sandpiper characteristics: a long, streamlined body, long legs, and a long narrow bill to probe for food.2 It is often described as robin-sized, reaching 23-25 cm (9-10 in) in length and having a wingspan ranging from 51-58 cm (20-23 in).3 Its plumage differs seasonally. The Red Knot has a dull grey plumage during winter and rusty red plumage on its chest and face with mottled brown scaling feathers on its head, hind neck, and wings in summer.3
The rufa Red Knot completes a long strenuous migration every year starting from its breeding areas in the central Canadian Arctic to its wintering areas in the US Gulf Coast, the Caribbean, and South America, making several stopovers along the way at traditional staging grounds along the US East Coast and South America. They can cover up to 15,000 km (9,300 mi) one way during their migration.1
