Black-Tailed Godwit

Fascinating facts about the Black-Tailed Godwit

• A black-tailed godwit's bill is longer than its entire head and body combined — up to 15 cm of needle-thin probe designed to pluck invertebrates from waterlogged soil without the bird needing to see them. They hunt by touch alone, sweeping their open bill through mud like a living sieve, feeling for the vibrations of hidden insects and crustaceans. This sensory gift lets them feed in complete darkness during the midnight sun of Arctic summers.
• These birds undertake one of the longest non-stop migrations on Earth: some populations fly 6,000 km from West African wintering grounds to breeding sites in Iceland in a single spring journey, fuelling this marathon with nothing but stored fat. Radar studies show they hit altitudes of 6,000 metres to slip above bad weather, and the entire crossing takes just 4–5 days of non-stop flight. A godwit weighing 200 grams burns through nearly half its body weight in fuel to reach the ice.
• Male black-tailed godwits perform one of nature's most frenetic courtship displays — rocketing into the air on rapid wingbeats while screaming a machine-gun call that carries across a kilometre of wet grassland. They climb to 100 metres, dive-bomb the ground, and repeat dozens of times in a single performance. The whole routine is a sound and light show designed to claim territory and warn rivals: this marsh is taken.
• In just 24 days, a newly hatched godwit chick goes from blind and helpless to a fully fledged flyer capable of keeping pace with its parents — one of the fastest developmental sprints in the bird world. The chicks must be airborne before the Arctic summer ends and insects vanish, forcing chicks and parents into an evolutionary arms race where a single week of delay can be fatal.
• The Eurasian subspecies has nearly vanished from its traditional breeding grounds in the Netherlands, where wetland drainage reduced the population from 100,000 pairs in 1900 to fewer than 40,000 today. Conservation groups are now rewetting grasslands and paying farmers to delay mowing until after nesting season — buying back the bird's habitat one soggy field at a time in a race against agricultural intensification.
