Tawny Frogmouth

Males and females look alike and are 35–53 cm (14-21 in) long. This very bulky species can weigh up to 680 grams (1.5 lbs) and, in overweight zoo specimens, up to 1400 grams (3.1 lbs). This species thus reaches the highest weights known in the Caprimulgiformes order.^[4] They have yellow eyes and a wide beak topped with a tuft of bristly feathers.^[5] They make loud clacking sounds with their beaks and emit a reverberating booming call.
Tawny Frogmouths hunt at night and spend the day roosting on a dead log or tree branch close to the tree trunk. Their camouflage is excellent — staying very still and upright, they look just like part of the branch.^[6]
The Tawny Frogmouth is almost exclusively insectivorous, feeding rarely on frogs and other small prey.^[2] They catch their prey with their beaks rather than with their talons, another way in which they are different from owls. Owls fly around at night hunting food, but Tawny Frogmouths generally remain sitting very still on a low perch, and wait for food to come to them. They catch prey with their beaks, and sometimes drop from their perch onto the prey on the ground. The bird's large eyes and excellent hearing aid nocturnal hunting. ^[6]
