The Tawny Frogmouth is one of Australia's most familiar and best-loved nocturnal birds, famous for its remarkable ability to disappear in plain sight. When alarmed by day it stretches upright, closes its eyes to slits and points its bill skyward, so that its mottled grey-brown plumage makes it look exactly like a broken, weathered branch. This trick fools most predators and countless passersby.
Although often called an owl, it is not one. Frogmouths belong to a separate group and lack the powerful grasping talons of owls, instead using their huge, wide, hooked bill to seize prey. They are found across almost the whole of Australia, including many towns and gardens, where pairs often stay together for life on a settled territory.
Look for a stocky, big-headed bird with an enormous wide bill, large yellow eyes and intricately patterned grey-brown plumage streaked and mottled to resemble bark. The upright, branch-mimicking posture when it feels threatened is a giveaway, as is the frog-like gape that gives the bird its name.
| Bill | Very broad, flat and hooked, wide like a frog's mouth |
| Plumage | Mottled and streaked grey-brown, sometimes rufous, mimicking tree bark |
| Eyes | Large and yellow, facing forward |
| Size | Stocky, 34 to 53 cm long, with a large head |
| Posture | Freezes upright with bill raised to resemble a broken branch |
| Feet | Small and weak, without the strong talons of true owls |
The Tawny Frogmouth's usual call is a soft, low, continuous 'oom-oom-oom' repeated in a rhythmic series, a mellow drumming hum that carries surprisingly far on still nights. When alarmed it may give a loud hiss or a sharp clacking of the bill, and pairs communicate with soft grunts and buzzing calls.
The Tawny Frogmouth is found throughout mainland Australia and Tasmania, occupying nearly every habitat except the densest rainforest and the most barren desert. It is common in open eucalypt forest and woodland, scrub, farmland, parks and suburban gardens, and its tolerance of human settlement makes it one of the country's most widely encountered nocturnal birds.
It feeds mainly on insects and other invertebrates, including moths, beetles, spiders, centipedes, slugs and worms, and it will also take small vertebrates such as frogs, lizards and the occasional small mammal or bird. It hunts by watching from a perch and pouncing onto prey on the ground or foliage, catching much of its food with its wide bill rather than its feet.
Pairs are typically monogamous and long-lasting, and they build a loose platform of sticks on a horizontal tree fork. The female usually lays two or three white eggs, and both parents share incubation, the male often sitting by day and the female by night. The downy chicks are brooded and fed by both adults and fledge within a few weeks, sometimes staying near the parents afterward.
- Papuan Frogmouth: A larger frogmouth of far northern Australia and New Guinea with a bigger bill and reddish eye
- Marbled Frogmouth: A rainforest frogmouth of eastern Australia, similar in shape but more finely marbled and orange-eyed
- Southern Boobook: A true owl of similar size often confused with it, but with a rounder head, hooked owl bill and strong talons
Is the Tawny Frogmouth an owl?
No. Despite its owl-like look and nocturnal habits it belongs to the frogmouth family, more closely related to nightjars. It catches prey with its wide bill rather than with talons.
How does the Tawny Frogmouth camouflage itself?
When threatened it stretches upright, closes its eyes to slits and lifts its bill so its bark-patterned plumage makes it look just like a broken branch, and it stays perfectly still to avoid detection.
What sound does a Tawny Frogmouth make?
Its typical call is a soft, low, repeated oom-oom-oom hum. When alarmed it can hiss loudly and clack its bill.
Are Tawny Frogmouths common in gardens?
Yes. They are widespread across Australia and readily live in parks and suburban gardens, often roosting in the same tree by day and hunting insects around lights at night.
