Jerdon's Nightjar
Caprimulgus atripennis
Like other nightjars, it has a wide gape, long wings, soft downy plumage and nocturnal habits. At 26 cm in overall length, it is almost a head's length larger than the Indian nightjar (C. asiaticus), and differs from that species in its barred tail, rufous rear neck, and wing bars. The vermiculations on the crown are fine giving it a nearly uniform shade. The collar is blackish. The male has a white patch on each wing. Otherwise, their cryptic plumage is mainly variegated buff and brown, as typical for the dark tropical woodland nightjars.

Square-tailed Nightjar
Caprimulgus fossii
Voice: This bird's call is a prolonged churring, which alternates between a fast and slow pace roughly every second. As such it differs from the similar long-tailed and slender-tailed nightjars which produce fast and slow churrs respectively.
