The Great Eared Nightjar: A Nocturnal Avian Wonder Found in Southeast Asia
The Great Eared Nightjar (Lyncornis macrotis) is a captivating nocturnal bird species native to the regions of Southeast Asia. Belonging to the Caprimulgidae family, this intriguing bird is divided into five distinct subspecies: Lyncornis macrotis macrotis, Lyncornis macrotis cerviniceps, Lyncornis macrotis bourdilloni, Lyncornis macrotis jacobseni, and Lyncornis macrotis macropterus. Let’s delve into more details about the remarkable Great Eared Nightjar.
These nightjars possess tufts of feathers atop their heads, creating an appearance that resembles ears. The geographical distribution of the various subspecies of Lyncornis macrotis varies, but their habitat preferences are generally consistent. They inhabit forests, scrublands, and grasslands, with breeding seasons differing across locations. Notably, these birds are abundant within their range and face no imminent threat of endangerment.
Feeding predominantly on insects, Great Eared Nightjars exhibit the unique ability to capture prey while in flight. Their distinctive calls serve as effective identification markers for these avian beings. Now, let’s explore the distribution, habitat, behavior, and other interesting aspects of the Great Eared Nightjar in greater detail.
Distribution and Habitat: The Great Eared Nightjar can be found across several Southeast Asian countries, including Bangladesh, India, Indonesia, Laos, Malaysia, Myanmar, the Philippines, Thailand, and Vietnam. Thriving in subtropical or moist lowland tropical forests, this species typically resides near rivers within these areas.
Behavior and Breeding: These nightjars are most active during dusk and nighttime hours, emitting a characteristic call that includes a sharp “tsiik” followed by a pause and a two-syllable “ba-haaww.” Their nesting involves a single egg laid in a ground scrape, and both parents take part in incubating the egg. The chicks possess excellent camouflage among leaf litter, contributing to their survival.
Subspecies and Taxonomy: The Great Eared Nightjar is divided into several subspecies, each with unique characteristics and distribution ranges. These include the nominate form macrotis (Vigors, 1831), bourdilloni (Hume, 1875), cerviniceps (Gould, 1838), jacobseni (Junge, 1936), and macropterus (Bonaparte, 1850).
Conservation and Outlook: The Great Eared Nightjar species, along with its subspecies, remains captivating due to its distinctive features. While the exact population size is uncertain, their stable trends indicate a positive outlook. These enchanting birds continue to grace the forests and landscapes of their native Southeast Asia, enriching the region’s diverse avian population.
In conclusion, the Great Eared Nightjar, with its enigmatic appearance and behaviors, represents an intriguing aspect of the avian world. As these remarkable creatures continue to thrive within their habitat, researchers and enthusiasts alike are afforded the opportunity to study and appreciate their unique characteristics and contributions to the natural world.
