Whimbrel Identification Guide

Key Field Marks

• Large shorebird, 40-46 cm (16-18 in), with a long, evenly down-curved bill.
• Mottled brown-and-buff upperparts and buffy, streaked underparts without strong barring.
• Bold head pattern: two dark lateral crown stripes separated by a pale central crown stripe, plus a dark eye-stripe - a key mark that separates it from other large curlews.
• Legs are blue-gray; in flight shows relatively plain wings without a strong wing pattern.

Separating It From Similar Species

• Long-billed Curlew: Noticeably larger with an even longer, more strongly curved bill, plain unstriped head, and warmer cinnamon-buff underparts and underwings.
• Bristle-thighed Curlew: Rare and restricted; paler and buffier overall with a paler, more contrasting rump/tail and a distinctive rolling call, unlike the Whimbrel's staccato whistle.
• Smaller curlews such as vagrant Little Curlew are much daintier with a shorter, more subtly curved bill and plainer plumage.

Habitat, Range & Season

• Breeds on open Arctic and subarctic tundra across North America, Europe, and Asia.
• On migration and in winter, found on coastal mudflats, sandy beaches, rocky shorelines, and sometimes short grasslands or agricultural fields.
• A long-distance migrant; winters along coasts from the southern U.S. through Central and South America, and similarly across Africa, southern Asia, and Australia in Old World populations.

Voice

• Distinctive flight call: a rapid, evenly pitched series of clear whistled notes, typically 5-7 in a row, often rendered as "ti-ti-ti-ti-ti-ti-ti" - frequently heard before the bird is seen.

Behavior

• Probes deeply in mud and sand for fiddler crabs and other invertebrates, often tilting its head to align the curved bill with burrows.
• On tundra breeding grounds, also eats insects and berries.
• Typically forages and roosts in loose flocks; migrating flocks often fly in a distinctive wedge or line formation.
