Dwarf Cassowary

Casuarius bennetti

The Dwarf Cassowary is a shy, prehistoric-looking inhabitant of the misty New Guinea highlands. Though it is the smallest of its kind, this flightless wonder is a powerful forest architect and a master of the deep jungle.

Behavior

The Dwarf Cassowary, also known as the Bennett’s Cassowary or Muruk, is the most reclusive and smallest of the three cassowary species. Primarily a solitary bird of the New Guinea highlands, it spends its days navigating the dense rainforest floor. While they appear heavy and grounded, they are remarkably agile, capable of jumping high into the air and swimming across wide rivers when necessary. They are highly territorial, and while they usually avoid human contact, they can become defensive if cornered or if a male is protecting his chicks.

Communication among these birds is fascinating; they produce low-frequency 'booming' sounds that can travel through thick vegetation where high-pitched sounds would be muffled. These sounds are often so low that they are felt as much as heard. During the breeding season, the female is the dominant figure, often mating with several males and leaving each one to incubate a clutch of large, green eggs alone for nearly two months.

Camera Tips

Capturing the Dwarf Cassowary on camera requires a deep understanding of their movement through the rainforest. These birds are creatures of habit and often use the same 'game trails' for years. Look for narrow paths in the undergrowth that are cleared of large debris, or areas where the soil has been disturbed by their large, three-toed feet. The best place to set a camera is near a known 'fruiting tree'—identify trees that are currently dropping soft, fleshy fruits, as a Dwarf Cassowary will return to these spots daily until the supply is exhausted.

Mount your camera at a height of about 24 to 30 inches (60-75 cm). This mid-chest height is perfect for capturing the bird's distinctive blue neck and casque without cutting off its powerful legs. Avoid pointing the camera directly toward a gap in the canopy, as the high-contrast light of the tropics can wash out the bird’s dark feathers. Instead, aim for a spot with consistent, dappled shade. Because these birds are sensitive to movement and strange objects, use a 'No-Glow' or 'Black Flash' infrared camera to ensure they aren't spooked by a visible light during low-light hours.

Setting your camera to video mode for at least 15-20 seconds is highly recommended for this species. Cassowaries move with a rhythmic, bobbing gait that is spectacular to see, and they often pause to inspect the ground or tilt their heads to listen for falling fruit. Use a high-speed SD card and a trigger speed of 0.3 seconds or faster; despite their size, they can disappear into the brush surprisingly quickly. If you are in a particularly humid area, use silica gel packets inside your camera housing to prevent fogging, which is the number one cause of ruined cassowary footage.

Frequently Asked Questions

Dwarf Cassowary are diurnal, meaning they are active during the day. They are most frequently spotted in the early morning shortly after sunrise and in the late afternoon before dusk, when they move between roosting sites and feeding grounds.

If you live within their native range in New Guinea or nearby islands, planting native fruit-bearing trees like wild figs or laurels is the best way to attract them. They are also drawn to reliable water sources like shallow ponds or slow-moving streams where they can drink and bathe.

Their diet consists mostly of fallen fruit, which they swallow whole. They also play a critical role in the ecosystem by dispersing seeds. When fruit is scarce, they will forage for fungi, insects, and small animals like frogs or rodents.

No, they are generally not found in suburban areas. They are very shy and prefer the cover of dense, primary rainforests or remote mountain slopes, far away from human noise and activity.

The Dwarf Cassowary is much smaller and lacks the fleshy red 'wattles' hanging from the neck that the Southern Cassowary possesses. Additionally, the Dwarf species has a lower, more triangular helmet (casque) compared to the tall, blade-like casque of the Southern Cassowary.
