The Whimbrel (Numenius phaeopus) is a large, long-distance migratory shorebird known for its distinct long, downward-curving bill, often seen probing mudflats for crabs and invertebrates. Roughly the size of an American Crow, they breed in the Arctic tundra and winter along coastal areas, making them a common sight on beaches and in salt marshes worldwide.
Here are key facts about Whimbrels:
Physical Characteristics: They are 30–45 cm in length, with streaked brown plumage, a pale belly, and a striped head. The most identifying feature is the long, decurved bill used to extract crabs from burrows.
Scientific Name & Meaning: Numenius phaeopus. Numenius is Greek for "new moon," referring to the crescent-shaped bill, and phaeopus means "dusky-footed" or "grey-footed".
Call/Voice: Their call is a loud, whistling "tittere-tittere-tittere" or a seven-note whistle, leading to nicknames like "Seven Seas Whistler".
Diet & Foraging: They primarily eat crabs, marine invertebrates, insects, and berries. They are often seen feeding on mudflats, sandy beaches, and sometimes in fields.
Migration & Habitat: These birds undertake immense journeys from Arctic breeding grounds (Canada, Alaska, Eurasia) to wintering grounds in South America, Africa, and Australia.
Predators & Threats: Predators of eggs and young include foxes, gulls, and jaegers. Their populations are threatened by habitat loss of coastal wetlands and, for the North American population, rapid warming in the Arctic.
Behavior: They are known to form large flocks for roosting at night, especially during the new moon high tides.
