Behavior

The Highland Guan is a secretive and primarily arboreal resident of Central America’s humid cloud forests. While they spend much of their time moving through the canopy with surprising agility for their size, they are most famous for the mechanical "wing-drumming" sounds males produce during display flights. This sound, which resembles a loud rattle or a wooden stick being dragged across a fence, is a hallmark of the highland forest soundscape during the breeding season.

These birds are generally shy and will quickly retreat into thick foliage if they sense a human presence. They are typically seen in pairs or small family groups. Despite their preference for the trees, they are frequently seen descending to the forest floor to forage for fallen fruits or to drink from small pools. Their social structure is relatively stable, and they tend to stick to established territories where food sources are reliable.

Camera Tips

To capture the Highland Guan on a trail camera, you must focus on the "transition zones" of the forest. Because they are shy, place your camera at the edges of clearings or near the base of known fruiting trees like wild avocados (Lauraceae). While they are often in the canopy, they regularly visit the ground to forage for fallen fruit. Mounting your camera 12 to 18 inches off the ground, angled slightly upward, will capture the best profile shots of them as they walk through the leaf litter.

Light is a major challenge in the Highland Guan's habitat. Cloud forests are notoriously dark and misty, which can trigger slow shutter speeds and result in blurry photos. Use a camera with a high-quality CMOS sensor and set your ISO to a higher range if possible. If your camera has a 'fast trigger' or 'sports' mode, enable it to freeze their movement. Additionally, since condensation is a constant threat in their humid environment, applying an anti-fog treatment to the outer lens or building a small protective 'porch' over the camera housing can prevent your shots from being ruined by moisture.

If you are trying to attract them to a specific spot in a backyard or garden near the forest edge, a low platform feeder stocked with overripe bananas or native berries can be highly effective. Place the feeder in a spot that has 'overhead cover'—these birds feel vulnerable in wide-open spaces. Finally, because their vocalizations and the male's wing-drumming are so distinctive, set your camera to 'Hybrid Mode' to capture both a high-resolution photo and a 15-second video clip with audio. The sound of their calls is often just as rewarding as the visual capture.

Similar Species

Species that look similar or are commonly confused with Highland Guan.

Crested Guan

The Crested Guan is larger, has white-speckled plumage on its chest, and lacks the intense sexual dimorphism of the Highland Guan.

Great Curassow

Much larger with a distinct curly crest on its head; males have a yellow knob on the bill rather than a red throat wattle.

Frequently Asked Questions

Highland Guans are diurnal, meaning they are active during the day. They exhibit peak activity in the early morning hours just after sunrise and again in the late afternoon before dusk as they forage for their final meals of the day.

If you live in a high-altitude region near their natural habitat, planting native fruiting trees or providing a platform feeder with fruit like bananas can attract them. They prefer gardens that maintain thick, natural cover and offer a water source.

Their diet consists mainly of fruits and berries found in the highland canopy. They are particularly fond of the fruit from trees in the laurel family, though they will also eat insects and small invertebrates found on the forest floor.

They are generally not found in dense suburban areas. However, they are frequently spotted in 'buffer zones' such as rural homesteads and shade-grown coffee plantations that border primary montane forests.

The male Highland Guan is easily distinguished by its solid black plumage and bright red throat wattle. Unlike the Crested Guan, it lacks the white spotting on the breast and has a more restricted range in the highlands.
