Eurystomus
''Eurystomus'' is a genus of roller, one of the two genera in that family of birds. The name means ‘broad mouth’, from the Greek ''eurus'' (, ‘broad, wide’) and ''stoma'' (, ‘mouth’). ''Eurystomus'' contains four broad-billed species, which breed in Africa, Asia and Australasia. Two species are restricted to Africa, one of which, the broad-billed roller, is migratory. The oriental dollarbird has a large distribution ranging from India to Japan and Australia and it too, is migratory over the northern and southern extremes of its range. The final species, the azure dollarbird, is endemic to the Moluccas in Indonesia. In general they are open country foragers, occurring in woodland, savanna and farmland. The azure dollarbird and the broad-billed roller are both associated with rainforests but nevertheless require open areas in which to forage. The species of the genus ''Eurystomus'' vary from the other genus of rollers, ''Coracias'', in having proportionally longer win ...

Dollarbird
The Oriental dollarbird (''Eurystomus orientalis'') is a bird of the roller family, so named because of the distinctive pale blue or white, coin-shaped spots on its wings. It can be found from Australia to Korea, Japan and India. Taxonomy The Oriental dollarbird was formally described by the Swedish naturalist Carl Linnaeus in 1766 in the twelfth edition of his ''Systema Naturae'' under the binomial name ''Coracias orientalis''. Linnaeus based his description on "Le Rollier des Indes" that had been described and illustrated by the French zoologist Mathurin Jacques Brisson in 1760. The type locality is the island of Java in Indonesia. The Oriental dollarbird is now placed in the genus ''Eurystomus'' that was introduced in 1816 by the French ornithologist Louis Jean Pierre Vieillot. A molecular phylogenetic study published in 2018 found that the azure dollarbird (''Eurystomus azureus'') was nested in a clade containing subspecies of the Oriental dollarbird.

Coraciidae
Coraciidae is a family of Old World birds, which is known as rollers because of the aerial acrobatics some of these birds perform during courtship or territorial flights. Rollers resemble crows in size and build, and share the colourful appearance of kingfishers and bee-eaters, blues and pinkish or cinnamon browns predominating. The two inner front toes are connected, but not the outer one. They are mainly insect eaters, with ''Eurystomus'' species taking their prey on the wing, and those of the genus ''Coracias'' diving from a perch to catch food items from on the ground, like giant shrikes. Although living rollers are birds of warm climates in the Old World, fossil records show that rollers were present in North America during the Eocene. They are monogamous and nest in an unlined hole in a tree or in masonry, and lay 2–4 eggs in the tropics, 3–6 at higher latitudes. The eggs, which are white, hatch after 17–20 days, and the young remain in the nest for approximately ano ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Broad-billed Roller
The broad-billed roller (''Eurystomus glaucurus'') is a member of the roller family of birds which breeds across tropical Africa and Madagascar in all but the driest regions. It is a wet season breeder, which migrates from the northern and southern areas of its range towards the moister equatorial belt in the dry season. Taxonomy The broad-billed roller was formally described in 1776 by the German zoologist Philipp Ludwig Statius Müller under the binomial name ''Coracias glaucurus''. The specific epithet is from Ancient Greek ''glaukos'' meaning "blue-grey". Statius Müller based his brief description on "Le Rollier de Madagascar" that had been described in 1775 by the French polymath Georges-Louis Leclerc, Comte de Buffon and illustrated by Edme-Louis Daubenton. The type locality is Madagascar. The broad-billed roller is now placed in the genus ''Eurystomus'' that was introduced in 1816 by the French ornithologist Louis Jean Pierre Vieillot.

Blue-throated Roller
The blue-throated roller (''Eurystomus gularis'') is a species of roller in the family Coraciidae. It is native to the African tropical rainforest. Taxonomy and systematics The blue-throated roller was formally described in 1819 by the French ornithologist Louis Jean Pierre Vieillot under its current binomial name ''Eurystomus gularis''. The specific epithet ''gularis'' is Modern Latin meaning "-throated". Vieillot based his description on a specimen in the Muséum National d'Histoire Naturelle in Paris which he mistaken believed had been collected in "Australasie"; the type locality has been designated as Senegal. A molecular phylogenetic study published in 2018 found that the blue-throated roller was most closely related to the broad-billed roller (''Eurystomus glaucurus''). Two subspecies are recognized: * ''E. g. gularis'' - Vieillot, 1819: Found from Guinea to western Cameroon * ''E. g. neglectus'' - Neumann, 1908: Found from south-eastern Nigeria and southern Cameroon ...

Azure Dollarbird
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 the Maluku Islands in Indonesia. Formerly, some authorities considered the azure dollarbird to be a subspecies of the oriental dollarbird. A molecular phylogenetic study by Ulf Johansson and collaborators published in 2018 found that the azure dollarbird was nested in a clade containing subspecies of the Oriental dollarbird (''Eurystomus orientalis''). Habitat The azure dollarbird's natural habitats are subtropical or tropical moist lowland forest and plantations. It is negatively affected by habitat loss. For some time, it was assumed to be decreasing in numbers quite rapidly and it was uplisted to Vulnerable in the 2000 IUCN Red List. However, more recently it was determined to be—although still declining—more common than previously believed and thus it has now been downlisted to Near Threatened i ...
