GROOOOAAAAA!!! Like owls, we potoos are nocturnal birds with large eyes and an upright posture, but that's where the similarities end. Potoos are related to nightjars and frogmouths, and like them, we have massive mouths. Potoos spend the day perching upright on tree stumps, and thanks to our coloration, we blend in with the stump and become hard to spot. At night, we become active and hunt insects and small vertebrates by locating them from our perch and taking flight to catch them! GROOOOOAAA!
