How to recognise it

The Common Potoo is a medium-sized nocturnal bird with cryptic plumage. Its mottled grey-brown colouration, complete with darker streaks and spots, provides excellent camouflage against tree bark. Large, yellow eyes and a wide, frog-like mouth are distinctive features.

Both sexes look similar, with no significant seasonal plumage changes. Juveniles resemble adults but may have a slightly paler, fluffier appearance.

Its song and calls

The Common Potoo's call is a haunting, descending whistle often described as 'poor-me-one'. This mournful sound, typically heard at night, consists of 4-5 notes that drop in pitch.

During the day, they may emit soft grunts or barks when disturbed.

When and where to see it

The Common Potoo is not recorded regularly in the UK, Ireland, the United States or Canada.

Worldwide: recorded regularly in 16 countries

Countries where it was recorded in at least 3 of the 6 years 2019–2024. Linked countries have their own bird list.

Tips for seeing it

  • Look for Potoos at night using a spotlight; their eyes reflect light
  • During the day, scan tree branches for bird-shaped 'stumps'
  • Listen for their distinctive, haunting call after sunset
  • Check known perches repeatedly, as they often return to the same spots

What it eats

Common Potoos are insectivores, primarily feeding on flying insects such as moths, beetles, and flying termites.

They hunt by sitting motionless on a perch, then swooping out to catch prey in flight with their large mouths. Occasionally, they may consume small bats or birds.

Nesting and breeding

The breeding season varies by region but often coincides with the dry season. During this time, Common Potoos form monogamous pairs. They do not build traditional nests, instead laying a single egg directly on a branch or tree stump.

The egg is white with brown and lilac spots, blending perfectly with the bark. Both parents take turns incubating the egg, which lasts about 30 days.

After hatching, the chick is cared for by both parents. It develops slowly, remaining in the nesting spot for about 40-50 days before fledging. Young Potoos can fly short distances at about two months old.

Behaviour

Common Potoos are masters of camouflage, often perching motionless on tree stumps or branches during the day, mimicking broken branches. At night, they become active, flying out to catch insects.

These solitary birds are rarely seen in groups except during breeding season.

Conservation

While the Common Potoo is listed as Least Concern by the IUCN, habitat loss due to deforestation poses a threat in parts of its range.

Conservation efforts focus on protecting tropical and subtropical forests, which are crucial for this species' survival.
