Adults of both sexes are about 43 cm (17 in) in length, including the long, broad tail. The adult male has a red head, breast, and lower undersides, with a blue band on the back of the neck between the red above and green on the back, the wings are green and each has a pale green shoulder band, the tail is green, and the rump is blue. The male has a reddish-orange upper mandible with a black tip, a black lower mandible with an orange base, and yellow irises. The plumage of the female is very different from the male having a green head and breast, a grey beak, and the pale shoulder band is small or absent. Juveniles of both sexes have brown irises and a yellowish beak, and otherwise resemble the female.<p>The two subspecies are A. s. minor, found at the northern limit of the species range and is similar in appearance to the nominate subspecies but smaller, typically about 5 cm (2 in) smaller in length.<p>On those rare individuals which have areas without melanin, feathers are orange to yellow. Such a bird can look startingly different from the more common scarlet and green variety.

Australian king parrots range from north and central Queensland to southern Victoria. They are frequently seen in small groups with various species of rosella. Further from their normal eastern upland habitat, they are also found in Canberra during winter, the outer western and northern suburbs of Sydney, and the Carnarvon Gorge in central Queensland.

Atlas Flycatcher
Ficedula speculigera
Very similar and closely related to European Pied Flycatcher. Males have mixed features of Collared and European Pied Flycatchers, but note very large white wing patch and big white forehead. Also note the absence of a white collar and pale rump patch on Atlas Flycatcher. Females are very difficult to distinguish, but note gray upperparts with paler rump and big white primary base patch. Song is a cheery up-and-down series, quite similar to that of European Pied. Calls subtly different from European Pied Flycatcher with a slightly more metallic "whit" and a slower tempo. Inhabits a variety of wooded habitats in the Atlas Mountains.
Pale-vented Pigeon
Patagioenas cayennensis
Large pigeon of marshy savannas, riversides, open areas with scattered trees, locally even in towns, such as Villahermosa, Mexico. Gray head contrasts with pinkish body, and whitish belly does not contrast strongly with plain grayish tail; compare darker Red-billed Pigeon, which often occurs in same areas but prefers drier and more forested habitats. Also note black bill of Pale-vented, and subtly distinctive song: after long introductory coo, repeated phrase is typically a 3-syllable "who’koo-koo", unlike 4-syllable "oo’koo-koo-koo" of Red-billed.
Jos Plateau Indigobird
Vidua maryae
A nest parasite that lays its eggs in the nests of Rock Firefinches. Breeding males are black with green iridescence and a pale brownish panel in the wings. Females and non-breeding males are streaky and brown on the back and pale below, with a bold facial pattern. The bill is whitish and the legs pale purple. A scarce, local, and poorly known species. Found in rocky areas within savanna. Given current knowledge, can only be confidently identified by vocalizations. Imitates the vocalizations of its host, Rock Firefinch, including soft “teew” whistles, a descending trill, “tep” notes, and “pit-pit-pit” calls. These are often mixed into a scratchy jumble of high-pitched notes.
