How do potoos raise their single egg?

Potoos are highly restricted nesters within the order Caprimulgiformes. Rather than building a traditional nest, they locate a tree branch or stub featuring a depression or crevice specifically sized to hold their single egg.12

Once the egg is laid, both parents participate in incubating it for a period of 30 to 35 days. After hatching, the semi-dependent nestlings are fed by both parents and remain in the nest until they are fully fledged. During the first half of the nestling period—which typically lasts 40 to 50 days—the young are sheltered by their parents. By the time this brooding phase ends, the young have developed juvenile plumage and are capable of mimicking the adult "broken branch" posture to remain camouflaged.12
