Long-Billed Curlew

Fascinating facts about the Long-Billed Curlew

• A long-billed curlew's beak curves downward so sharply it looks broken — but that 8-inch probe works like a living tweezers, reaching into burrows and mud crevices no other shorebird can access. The beak contains sensory pits that detect vibrations from hidden prey, letting the bird hunt by touch alone in complete darkness. It's evolution's answer to a specialist niche: where other shorebirds peck at the surface, curlews fish from depths.
• Male curlews perform one of North America's most haunting courtship displays: they fly 100 feet into the air, then spiral downward while releasing a two-second bubbling whistle that carries across grasslands for nearly a kilometre. The sound comes from air rushing through their wings during a controlled stall — a combination of aerodynamics and vocal gymnastics. Grassland birders say a spring morning with curlews calling is unforgettable because the birds themselves seem to understand the drama they're creating.
• Long-billed curlews vanished from 95% of their historical range between 1850 and 1950 as North American grasslands were ploughed for crops. Fewer than 20,000 pairs remained by the 1980s. Today, conservation breeding programs and grassland restoration have brought populations back to roughly 140,000 birds — a quiet rewilding story that works because curlews need very little: native prairie, ground-nesting space, and undisturbed breeding seasons from March to July.
• A curlew chick leaves the nest within 24 hours of hatching and must immediately find food on its own — no parental feeding, just a mother who leads and teaches. At 5 weeks old the fledglings can fly, but they don't leave North America until mid-August, timing their departure by the waning daylight. Young birds then fly 3,000 kilometres non-stop to wintering grounds in Central America and northern South America, navigating routes they've never seen before using only instinct.
• Curlews are ecological engineers: their deep probing and ground-nesting behaviour loosens prairie soil, and their presence is so important that grassland health surveys now use curlew populations as a barometer for overall ecosystem recovery. Where curlews thrive, you'll find healthy invertebrate communities, intact native grasses, and water tables that support amphibians and small mammals — proof that saving one specialist species can mean saving an entire landscape.
