Little Stint

Fascinating facts about the Little Stint

• At just 20 grams — lighter than a AA battery — the little stint is a shorebird that crosses the Sahara Desert twice a year without refueling. It fattens up in African wetlands before departing on a non-stop flight of over 4,000 km to breed in the Arctic tundra, burning through its entire body weight in fuel to survive the journey. That metabolic feat, compressed into a bird you could hold in your palm, reveals how evolution can pack a marathon runner's endurance into a frame the size of a sparrow.
• A little stint's eyes are positioned so far back on its skull that it can see 360 degrees without turning its head — even looking backward and upward at once. This near-total wrap-around vision is a hunter's superpower on open mudflats where predators come from the sky, and it lets flocks detect a peregrine falcon's dive milliseconds faster than their neighbors can.
• In the Arctic breeding grounds where little stints nest, they lay four eggs in a shallow scrape of gravel — and within 24 hours of hatching, the chicks are already walking and hunting for themselves while parents keep watch from above. No feeding required. This 'precocial' strategy means parents can abandon their young within days and flee south while food is still plentiful, hedging against the crushing speed of the Arctic season's collapse.
• The little stint and its near-identical cousin the Temminck's stint coexist in the same mudflats and breed in the same tundra, yet almost never interbreed — a boundary maintained entirely by tiny shifts in the timing of their courtship calls. A difference of just 50 milliseconds in a male's song pitch keeps two species from merging, showing how the most fragile borders in nature run along the razor edge of sound.
• Each autumn, little stints undertake one of nature's most extreme population bottlenecks: nearly the entire global population — hundreds of thousands of birds — funnels through the Gulf of Guinea's coastal wetlands in West Africa over just four weeks. A single drought, oil spill, or coastal development in that narrow window could wipe out a quarter of the world's breeding population before they even reach their African wintering grounds.
