Australian Owlet-nightjar

Aegotheles cristatus

Smallest Australian nocturnal bird, primarily gray-brown with large eyes, relatively long tail, and "whiskers" on the face. During the day, usually seen only if one is peering out of a roosting hollow. Small size and near lack of eyeshine make this species also difficult to locate at night; the call, a loud, brief "chew," is the best way to locate one.

The Australian owlet-nightjar (Aegotheles cristatus) is a nocturnal bird found in open woodland across Australia and in southern New Guinea. It is the smallest nocturnal bird found in Australia, making it prone to predation. It is colloquially known as the moth owl or fairy owl and Jarlajirrpi by the Warlpiri people. It is the most common nocturnal bird in Australia. Despite suffering from predation and competition by introduced species, it is not considered threatened.

New Guinea Bronzewing

Henicophaps albifrons

A large, distinctive pigeon of lowland and montane forest. Long bill, white forehead and dark reddish neck. Metallic bronze, green and blue bands in the wing. Feeds on the forest floor and perches upright on a branch, bobbing its head. Shy and difficult to see. Thick-billed Ground-Pigeon is a similar size but has a white cheek rather than forehead and lacks iridescence in the wing. Voice, a repeated series of rapid, upslurred “woop” notes.

Semicollared Flycatcher

Ficedula semitorquata

Very similar to other black-and-white small flycatchers. Male differs from Collared and Pied Flycatchers in thinly connected black crown and mantle, and white median coverts. Female is identified by the double pale wingbars and less extensive white areas on the wing. Breeds in mountains and hills in mixed or deciduous forest. During migration and on wintering grounds, found in various open wooded areas, from riparian forests to acacia savannas. Song is a high-pitched musical whistle interspersed with short scratches. Call is a short thin “seep” note and short metallic tacks.

Pale-bellied Mourner

Pale-bellied Mourner

Rhytipterna immunda

Medium-sized, dull flycatcher; resembles a Myiarchus but has smaller bill, rounder head, and little contrast between breast and belly. Locally distributed and poorly known; found in seasonally inundated and scrub woodlands on weathered white sands. Inconspicuous and best located by voice; behaves sluggishly, sallying to foliage for insects; also eats fruit. May be found alone or in loose association with other species. Distinctive voice is a rich, slurred whistle, Schiffornis-like in quality and unlike any other species in habitat.
