Potoos or Patoo birds, are sometimes called Poor-me-ones, after their haunting calls & are related to the nightjars & frogmouths. These are nocturnal insectivores which lack the bristles around the mouth found in the true nightjars. They hunt from a perch like a shrike or flycatcher. During the day they perch upright on tree stumps, camouflaged to look like part of the stump. The single spotted egg is laid directly on the top of a stump.
