Quoy & Gaimard, 1830
There are three subspecies: P. p. papuensis, P. p. baileyi and P. p. rogersi
The Papuan frogmouth is the largest of frogmouths in terms of length. Average sizes indicate that it only falls behind the Neotropical Great Potoo and Oilbird (if the latter is a true member of the order) among the largest species in the order Caprimulgiformes. On average these birds are about 53 cm (21 in), with a range of 50 to 60 cm (20 to 24 in). This species was found to average 414 g (14.6 oz) in males and 314 g (11.1 oz) in females, with a total range of 290 to 570 g (10 to 20 oz). The tawny frogmouth is smaller on average than this but is capable of reaching higher maximum weights. The Papuan frogmouth has a bulbous bill, red eye, cream eyebrow, long tail and dark wings. The male of the species is slightly larger, darker and marbled in appearance. The female is more rufous in appearance.
P. p. baileyi is smaller, and darker. P. p. rogersi is larger and paler.
Distribution and habitat
The call is a resonant 'ooom' or a laughing hoot. It is usually heard after dusk and before dawn.
It has been speculated that the Papuan frogmouth may secrete a substance in its mouth that attracts flies. According to a number of observers it is able to wait with its mouth open and flies enter to investigate the odor.
