The bird that disappears by pretending to be a branch
This bird can vanish in plain sight by pretending to be a broken branch.
Which one is REALLY true about the Potoo?
The short version
The potoo is a nocturnal bird that by day points its head up, freezes on a snapped branch, and its mottled feathers make it look exactly like a dead stump. At night it opens enormous yellow eyes and a huge gaping mouth to catch insects — and special slits in its eyelids let it watch while 'asleep'.

The full story
This bird can disappear completely while sitting right in front of you. Meet the potoo, a nocturnal master of disguise from the forests of Central and South America. By day, it perches on a broken branch, points its head straight up, half-closes its eyes, and freezes. Its mottled grey-brown feathers blend in so perfectly that it looks exactly like a dead, snapped-off stump, and predators stare right past it. But when night falls, the act drops. It opens enormous yellow eyes, almost comically huge, and unhinges a massive gaping mouth to snatch moths and beetles straight out of the air. Even with its eyes shut, special slits in its eyelids let it keep watch for danger without ever breaking the disguise. By day a piece of wood, by night a wide-eyed hunter. Follow for more weird animal facts.
A potoo's feathers are dappled in the same greys, browns and blacks as weathered bark, and those blotches break up its bird-shaped outline so a predator's brain reads 'wood' instead of 'food.' Stretching tall with its bill pointed up, flattening its feathers, and freezing on a snag about as wide as its body erases the three clues hunters look for: an outline, an eye, and movement. Scientists call this 'masquerade' — the bird isn't just hard to see, it is mistaken for a dead branch. Because open eyes would give the trick away, it keeps its eyelids shut and peeks through tiny notch-like slits in them, so it can watch for danger without breaking the disguise.
