Greater Band-winged Nightjar
The Greater Band-winged Nightjar (Systellura longirostris) Read in Spanish
Appearance: The Greater Band-winged Nightjar is a medium-sized nightjar with cryptic plumage that provides excellent camouflage against its typical forest floor habitat. It has a distinctive pattern of bold white wing bars and white tips on the tail feathers. The bird has a long, slender bill and a wide mouth adapted for catching flying insects at dusk and dawn.
Habitat: In Colombia, the Greater Band-winged Nightjar is primarily found in lowland and foothill forests, especially in humid and tropical forest environments. It prefers areas with dense undergrowth, leaf litter, and open spaces for foraging. These nightjars are often associated with mature forests and forest edges, where they can roost and nest on the ground.
Behavior: Greater Band-winged Nightjars are nocturnal birds that are most active during the twilight hours. They are skilled aerial foragers, feeding on insects such as moths, beetles, and flying ants. These nightjars have a distinctive flight pattern with agile maneuvers and silent wingbeats as they hunt prey in the dim light of dusk and dawn.
Breeding: Breeding behavior in Greater Band-winged Nightjars involves courtship displays, territorial calls, and nesting on the forest floor. The female usually lays two eggs directly on the ground, relying on their cryptic plumage to conceal the nest. Both parents share nesting duties, with the male often incubating the eggs during the day.
Conservation Status: The conservation status of the Greater Band-winged Nightjar in Colombia is not well-documented due to limited research and monitoring efforts.
