Great Eared-nightjar

The Great Eared-nightjar (Lyncornis macrotis) is a remarkable nocturnal bird known for its distinct silhouette and elusive nature. As the largest member of the nightjar family, it is a master of camouflage, often going unnoticed by casual observers during the daylight hours.

Measuring between 31 and 41 cm in length, the Great Eared-nightjar is a substantial bird. Its plumage is primarily a cryptic brown, intricately patterned with streaks and mottling that allow it to blend perfectly into tree bark or leaf litter. Accenting its darker feathers are shades of buff, providing a soft contrast that aids in its disguise. Its most iconic feature is the pair of long, ear-like tufts of feathers extending from its head, which give the species its common name.

This species is primarily found throughout Southeast Asia, ranging from India and the Philippines to Indonesia. It prefers forested areas, including evergreen forests, forest edges, and sometimes scrublands near water sources, where it can find ample cover during the day.

As an insectivore, the Great Eared-nightjar is active at night, hunting on the wing. Its diet consists almost exclusively of flying insects, such as moths, beetles, and termites, which it catches mid-air using its wide, bristled gape.

Great Eared-nightjars do not build traditional nests. Instead, they lay a single egg directly on the ground or on a thin layer of leaf litter in a shaded, secluded area. Both parents participate in the incubation process, relying heavily on their cryptic coloration to protect the egg from predators.

Primarily nocturnal, these birds spend their daylight hours resting motionless on tree branches or the forest floor. They are known for their distinct, two-note call that echoes through the night forest. During flight, they are agile and silent, a necessity for their predatory lifestyle.

The Great Eared-nightjar is currently classified as Least Concern by the IUCN. While their populations are generally stable, they face ongoing threats from habitat loss and deforestation in parts of their range.

1. It is the largest species within the Caprimulgidae family.
2. The "ear" tufts are not ears at all, but elongated feathers used for camouflage and signaling.
3. Their eyes reflect light strongly, making them easier to spot with a flashlight at night.
4. They possess a very wide mouth surrounded by stiff bristles, which act like a net to trap insects.

To spot a Great Eared-nightjar, visit forest edges at dusk or dawn. Use a high-quality spotlight or headlamp to scan the treetops or the ground; look for the characteristic 'eyeshine' reflecting back at you. Patience and silence are key, as these birds are easily startled by sudden movements.

The Great Eared-nightjar is a true marvel of evolutionary adaptation. Its ability to thrive in the darkness, combined with its stunning cryptic appearance, makes it a highly sought-after sighting for birdwatchers. Protecting their forest habitats remains essential to ensuring these unique nocturnal hunters continue to roam the night skies.
