Square-tailed Drongo-Cuckoo

Surniculus lugubris

A small, slim black cuckoo rather similar to Black Drongo but smaller, with a curved bill. Adult black with white bars in the undertail, shorter-tailed juvenile deep blackish gray with bright white dots in wings and flanks. Rather sedentary and difficult to see in tangled vegetation of scrubby and edge habitats in lowland and foothill forests. Song a loud, vibrant, rapid series of ascending hoarse whistles.

Identification

It can be easily distinguished by its downcurved beak and the white barred vent and outer undertail, and the tail only notched with slightly flared tips. In flight a white wing-stripe is visible from below. It is a brood parasite on small babblers. It is not known how or whether the drongo-like appearance benefits this species but it is suspected that it aids in brood-parasitism just as hawk-cuckoos appear like hawks.<p>The square-tailed drongo-cuckoo was formerly considered conspecific with the fork-tailed drongo-cuckoo (together known as the Asian drongo-cuckoo), but vocal and morphological differences suggested that the species should be split. That treatment is followed here.

Gray Falcon

Gray Falcon

Falco hypoleucos

Seldom-seen pale gray falcon of inland Australia found in arid grassland and woodland habitats, where it sometimes perches high on communication towers. Pale gray upperparts and white underparts, with faint dark streaks below. Legs fully feathered (unlike the long, bare legs of Brown Falcon). In flight, outer upperwing (“hand”) is noticeably darker than the inner wing and back. Wings not as pointed as hobby or Peregrine Falcon. Pale inland Brown Falcons are often misidentified as this species: note that Gray Falcon is unlikely to be seen perched in low bushes or feeding from the ground.

White-headed Woodpecker

White-headed Woodpecker

Leuconotopicus albolarvatus

Distinctive woodpecker, unlikely to be confused with any other species. Almost entirely black with white head and small white wing patch. Males have red patch on back of crown; sexes otherwise alike. No other woodpecker shows clean white head and lack of patterning on back or belly. Found in coniferous forests, often in mountains. Usually seen in pairs or family groups. Listen for sharp "peek" notes, often rapidly doubled or tripled.

Rock Partridge

Rock Partridge

Alectoris graeca

This well-marked European endemic prefers rocky slopes and dry areas of hill and montane forest. Up to 3,000 m (10,000 ft), but can be found in lower-lying open flat areas with sparse grass and low bushes in some regions. Highly territorial and vocal, giving an irregular series of "chick chek pe-ti-chek chi-chek" notes, particularly in the early morning. Often runs away rather than flying. Throat is white, while similar looking Chukar has a creamy throat; virtually no overlap in range with other similar species.
