The two Asiatic species are the blue or Indian peafowl originally from the Indian subcontinent, and the green peafowl from Southeast Asia. The Congo peafowl, native only to the Congo Basin, is not a true peafowl. Male peafowl are known for their piercing calls and their extravagant plumage. The latter is especially prominent in the Asiatic species, which have an eye-spotted "tail" or "train" of covert feathers, which they display as part of a courtship ritual.
The functions of the elaborate iridescent coloration and large "train" of peacocks have been the subject of extensive scientific debate. Charles Darwin suggested that they served to attract females, and the showy features of the males had evolved by sexual selection. More recently, Amotz Zahavi proposed in his handicap principle that these features acted as honest signals of the males' fitness, since less-fit males would be disadvantaged by the difficulty of surviving with such large and conspicuous structures.

The thrushes are a passerine bird family, Turdidae, with a worldwide distribution. The family was once much larger before biologists reclassified the former subfamily Saxicolinae, which includes the chats and European robins, as Old World flycatchers. Thrushes are small to medium-sized ground living birds that feed on insects, other invertebrates, and fruit. Some unrelated species around the world have been named after thrushes due to their similarity to birds in this family.
The mynas (/ˈmaɪnə/; also spelled mynah) are a group of birds in the starling family (Sturnidae). This is a group of passerine birds which are native to Iran and Southern Asia, especially Afghanistan, India, Pakistan, Bangladesh, Nepal and Sri Lanka. Several species have been introduced to areas like North America, Australia, South Africa, Fiji and New Zealand, especially the common myna, which is often regarded as an invasive species. It is often known as "Selarang" and "Teck Meng" in Malay and Chinese respectively in Singapore, due to their high population there.
Kiwi (/ˈkiːwiː/ KEE-wee)[4] are flightless birds endemic to New Zealand of the order Apterygiformes. The five extant species fall into the family Apterygidae (/ˌæptəˈrɪdʒədiː/) and genus Apteryx (/ˈæptərɪks/).[5] Approximately the size of a domestic chicken, kiwi are the smallest ratites (which also include ostriches, emus, rheas, cassowaries and the extinct elephant birds and moa).
The roadrunners (genus Geococcyx), also known as chaparral birds or chaparral cocks, are two species of fast-running ground cuckoos with long tails and crests. They are found in the southwestern and south-central United States, Mexico and Central America,[2][3] usually in the desert. Although capable of flight, roadrunners generally run away from predators. On the ground, some have been measured at 32 km/h (20 mph).
The blue jay (Cyanocitta cristata) is a passerine bird in the family Corvidae, native to eastern North America. It lives in most of the eastern and central United States; some eastern populations may be migratory. Resident populations are also in Newfoundland, Canada; breeding populations are found across southern Canada. It breeds in both deciduous and coniferous forests, and is common in residential areas. Its coloration is predominantly blue, with a white chest and underparts, and a blue crest; it has a black, U-shaped collar around its neck and a black border behind the crest. Males and females are similar in size and plumage, and plumage does not vary throughout the year. Four subspecies have been recognized.
The azure dollarbird (Eurystomus azureus) also known as the azure roller, purple dollarbird or purple roller, is a species of bird in the family Coraciidae. It is endemic to North Maluku in Indonesia. Formerly, some authorities considered the azure dollarbird to be a subspecies of the oriental dollarbird.
