The blue-eared kingfisher is found in Asia, ranging across the Indian subcontinent and Southeast Asia. It is found mainly in dense shaded forests where it hunts in small streams. It is darker crowned, with darker rufous underparts and lacking the rufous ear stripe of the common kingfisher which is found in more open habitats. A number of subspecies have been described that differ in measurement and colour shade. Adult males have an all dark bill while females have a reddish lower mandible.

The Oriental cuckooshrike is a species of bird in the family Campephagidae. It is widely distributed from the Himalayas through Southeast Asia to east China and Taiwan. It is also found on the islands of Java and Bali in Indonesia. Its natural habitat is subtropical or tropical moist lowland forest. The range of this species was formerly restricted to Java and Bali and had the English name "Javan cuckooshrike".
The Sunda crow, formerly known as the slender-billed crow, is a passerine bird of the family Corvidae, in the genus Corvus. It is found from Malaysia to Borneo. The violet crow has been shown to be distinct genetically and separated as Corvus violaceus. The small crow has been split as Corvus samarensis and the Palawan crow has also been split as Corvus pusillus.
The banded broadbill is a species of bird in the Eurylaimidae typical broadbill family found in Mainland Southeast Asia and the Greater Sunda Islands. It is sometimes split into two species, one including only the nominate subspecies, E. j. javanicus, and one including all the remaining subspecies. It inhabits a variety of forests, along with forest edge, rubber plantations and Falcataria falcata groves, mainly in lowland areas. A striking, large-bodied bird with a length of 21.5–23.0 cm (8.5–9.1 in), it is unlikely to be mistaken for another species. The broadbill is mostly purplish-red, with yellow-streaked black wings, a bright blue beak, a blackish face and greyish chin and upper breast. Females can be told apart from males by their lack of a black neckband, although these are indistinct in Bornean and Javan males. Despite its conspicuous appearance, the bird is usually hard to see due to its sluggishness and is usually only noticed when it vocalises.

The ivory-billed woodpecker is a woodpecker native to the bottomland hardwood forests and temperate coniferous forests of the Southern United States and Cuba. Habitat destruction and hunting have reduced populations severely, such that the last universally accepted sighting in the United States was in 1944, and the last universally accepted sighting in Cuba was in 1987. Sporadic reports of the persistence of the species since these dates are controversial, and most sources agree that it is likely extinct.
The yellow-eared barbet is an Asian barbet native to Java and Bali. It inhabits shrubland and forest up to an altitude of 2,000 m (6,600 ft).
