Silky-tailed Nightjar Antrostomus sericocaudatus

Large nightjar with dark plumage and long wings. Has blackish-brown broad spots and streaks above and is brown and white spotted below. Note the buffy collar on the nape. Males have a white tipped tail while the female’s tail tips are buffy. Found at the forest edge and in the forest interior, preferring thickets and areas with a bamboo understory. The song is a mournful and undulating “doh, wheo, eeo,” often repeated for long periods.
