Great Potoo

Identification

The Great Potoo is the largest species in the potoo family, a nocturnal bird with a distinctly owl-like appearance despite belonging to a different order. It is characterized by a large head relative to its body, large dark brown eyes, and a short but broad beak. The bird measures 480 to 600 mm in length with a wingspan averaging around 735 mm, and weighs between 360 and 650 grams. Its plumage combines white, gray, black, and burgundy tones, with distinctive white bars crossing the elongated tail. The elliptical wings and overall coloration provide excellent camouflage against tree bark and wood.

Range & Habitat

This species is widely distributed across the Neotropics, ranging from southern Mexico through Central America and down through most of South America, reaching as far as southeastern Brazil and Bolivia. The Great Potoo inhabits humid to semi-humid forested regions, preferring dense lowland forests, forest edges, and clearings, though it also ranges into foothills up to approximately 1,500 meters elevation. It adapts to second-growth woodlands, open plantations, and areas near meadows, but always requires substantial trees for its characteristic camouflaged perching.

Behaviour & Diet

Strictly nocturnal, the Great Potoo is a solitary and shy predator that hunts by perching on high branches—typically 20 to 30 centimeters in diameter and higher than 12 meters above ground during the day. When night falls, it descends to lower perches around 1.5 meters to hunt, using a hunting technique called sallying: it spots prey from its exposed perch, darts out to capture it, and returns to the same branch. Its diet consists primarily of large flying insects including beetles, katydids, crickets, and grasshoppers, with occasional birds and bats. The species is particularly renowned for its distinctive moaning growl vocalized throughout the night, creating an unsettling atmospheric presence in tropical landscapes. During the day, the bird perches upright on tree stumps, relying on camouflage that mimics the wood itself rather than coloration alone.

Best Time & Places to See It

The Great Potoo is most active at night and can be located by the distinctive eye-shine reflection when light is directed at vertical perches. Breeding occurs typically from February to August, though timing varies across its range. The species is uncommon overall but occurs frequently in less disturbed forests, making primary tropical forest reserves the most promising locations. Look near thick tree branches at least 10 meters above ground, where birds are most likely to roost and nest. Night-time forest walks with a headlamp offer the best chance of observing this elusive nocturnal hunter.

Photography Tips

Photographing the Great Potoo requires patience and nighttime field work. A headlamp or flashlight will reveal the bird's position through eye-shine reflection as it sits vertically on perches, stumps, or angled tree trunks. Wide-angle lenses work well for capturing the bird in its natural daytime perching position among tree branches. For nocturnal shots, use high ISO settings and fast lenses to work with available light. Early morning hours may also yield opportunities before the bird settles into its daytime roost. Exercise caution during breeding season (February to August) to avoid disturbing nesting birds and their single eggs, which rest in shallow depressions on thick branches high above ground.
