Blue-Winged Teal

Fascinating facts about the Blue-Winged Teal

• Blue-winged teals migrate further south than almost any other North American duck — birds breeding in Canada vanish entirely each winter, crossing the Caribbean to reach wetlands in Central and South America. A single bird might log 14,000 kilometres annually, yet weigh only 350 grams: like a tennis ball commuting between continents.
• The male's head is the colour of chocolate, but his face is a pale crescent moon — a pattern so specific that ornithologists can identify individual birds from photographs alone. This white facial mask evolved as a signal to females; males with brighter crescents breed earlier and produce more chicks.
• Both male and female blue-winged teals can rotate their eyes independently and see nearly 340 degrees around their heads without moving. They hunt by tipping headfirst into shallow water to filter insects and seeds through comb-like teeth lining their beaks — a technique borrowed from dabbler ancestors that makes them one of the few ducks that eat as much plant matter as meat.
• Females nest in upland grasslands far from water, sometimes 50 metres from the nearest pond, and raise ducklings alone — the male abandons her mid-incubation. This high-risk strategy works because their shallow-water habitat floods seasonably; the ducklings fledge and flee before wetlands dry up, unlike ducks that nest beside permanent water.
• In just 60 years, blue-winged teal populations plummeted 40 per cent as prairie wetlands were drained for agriculture. Recent conservation buyback programs that restore grassland and water across the Great Plains have reversed the decline, proving that lost habitat can be recovered — and that small ducks with crescent moons on their faces are worth the effort.
