Emperor Fairywren
Malurus cyanocephalus
The common fairywren of lowland and foothill forest edge and thickets. A small, long-tailed bird with a dark blue mask, a pale blue crown, and a cocked tail. Male has otherwise uniform deep blue plumage, and the female rufous brown upperparts with a white breast. Forages in small groups in thick undergrowth. Female similar to Wallace’s Fairywren but Emperor lacks the white wing bars and facial stripe. Song is a jumble of warbled notes, and call a dry “churr.”
Identification
It is the largest fairywren, being 13–16 cm (5.1–6.3 in) long and weighing 12–17 g (0.42–0.60 oz). Males of the nominate race have light royal blue crowns. The forehead, lores, and the side of the head up till the narrow collar is black. The upper back, along with the scapulars and uppertail-coverts is a deep turquoise-blue, with the lower back being blue-black. The upperwing and the tail are blackish-blue with tinges of blue, and the throats and underparts are a navy blue in color. It has dark brown eyes, black bill, and dark grey-brown legs. Females of the nominate race have a head that looks similar to the male, but have chestnut upperparts, white underparts, deep blue throats, and a black tail with whitish tips. They also have lighter and more mid-brown legs, along with duller crowns that are deeper in colour. Juveniles look like females, but have a dusky head, rusty brown upperparts, and entirely white underparts. M. c. mysorensis differs slightly in appearance with its crown being cobalt blue instead of royal blue, and M. c. bonapartii is slightly darker than the nominate race.<p>Its songs are a reel that are preceded and followed by sets of 3 notes. This call is frequently given by groups of emperor fairywrens while they are foraging. The contact calls for the bird are "tst-tst-tst-tst”, with the alarm call being “tschik”.
Taxonomy
The emperor fairywren was originally described by Jean Quoy and Joseph Gaimard in 1830 based on specimens collected by them in northwestern New Guinea in 1827 on a voyage of the l'Astrolabe. They mistook the specimens as todies, and described the species as Todus cyanocephalus. In 1854, Charles Lucien Bonaparte recognised that the species was not a tody, and created the genus Todopsis, making the emperor fairywren its type species. In 1859, George Gray described Todopsis bonapartii as a species on the basis of specimens from the Aru Islands, while Adolf Meyer described Todopsis mysorensis on the basis of specimens from Biak in 1874. However, Walter Rothschild and Ernst Hartert included them as subspecies of T. cyanocephalus, while adding T. c. dohertyi as a fourth subspecies from northern New Guinea on the basis of differences in the colour of the females. In 1982, Richard Schodde moved the emperor fairywren from Todopsis to Malurus and included dohertyi as a part of M. c. cyanocephalus.<p>The generic name Malurus is from the Greek malos (soft) and oura (tail), while the specific epithet comes from the Greek kuanos (dark blue) and kephalos (headed). Alternate names include the blue fairywren, blue wren-warbler, emperor wren, imperial fairywren, imperial wren, and New Guinea blue-wren.<p>The emperor fairywren is one of 11 species in the genus Malurus. Within the genus, it is variously said to be most closely related to the chestnut-shouldered wrens and a group comprising the bi-colored and blue wrens. Like other fairywrens, the emperor fairywren is not related to the true wrens. The fairywrens were previously classified in the Muscicapidae and the Sylviidae before being put in the newly established Maluridae in 1975. DNA evidence has shown the Maluridae to be most closely related to the Meliphagidae and the Pardalotidae in the superfamily Meliphagoidea.<p>Three subspecies of the emperor fairywren are recognized:

Range and habitat
It is found on New Guinea and the Aru Islands. It is found in tropical lowland, forests, wetlands, and degraded former forests. They inhabit dense secondary growth that occurs at the edges of forest, along with forest openings, riversides, roadsides and overgrown gardens. They are not as affected by habitat disturbance and appear to like disturbed habitats like gardens and parks.

Behavior
The emperor fairywren feeds mainly on arthropods. They eat beetles, bugs, moths, grasshoppers, and spiders. Foraging is conducted in noisy family groups, with the insects foraged from leaves, palm fronds and branches within 1 m (3.3 ft) of the ground.<p>Little is known about the breeding habits of the emperor fairywren, but as juveniles have been recorded from March-December, it probably breeds throughout the year. They are socially monogamous but sexually promiscuous, remaining paired throughout the year. It is a cooperative breeder, having helpers, most frequently former chicks, in pairs or small groups to help raise young.<p>The only observed nest was gourd-shaped with a side entrance, placed 1 m (3.3 ft) off the ground in a bush and containing 4 young. The nest was made out of strips of fern and leaves which were woven together with moss.

Other Birds
Baudin's Black-Cockatoo
Zanda baudinii
Black cockatoo with white ear patch and white tail panel. Inhabits moist eucalypt forest in the southwestern corner of Western Australia, where it eats seeds from large seed pods of Marri and Karri trees. Unlikely to be observed out on the coastal sand plains of Perth. Very similar to Carnaby’s Black-Cockatoo but with much longer, pointed upper mandible. Calls include mournful wailing cries that are more clipped than those of Carnaby’s.
Rufous-throated Honeyeater
Conopophila rufogularis
Small honeyeater with a distinctive red-brown throat patch, white underparts, gray head, brown back, and yellow wing patch. Juveniles lack the rusty throat patch but may have traces of reddish coloration. Typically found in forest and woodland next to rivers or water sources. Endemic to northern Australia.
Dusky Sunbird
Cinnyris fuscus
A small sunbird. The male is dark overall, with a pale lower belly and orange tufts at the shoulder that are sometimes hidden. The female is plain gray-brown with a paler lower belly. Singles and pairs prefer arid scrub and savanna, feeding on insects and nectar. The species is nomadic and can irrupt in large numbers into areas where it is normally irregular, often on the fringes of its range. The female Dusky Sunbird has paler underparts than the similar female Southern Double-collared Sunbird.
