There are 15 recognised subspecies. Of these three occur on mainland New Guinea, 11 on the Maluku Islands to the west of New Guinea, and two on other islands.[5]

The Biak paradise kingfisher (Tanysiptera riedelii) and the Kofiau paradise kingfisher (Tanysiptera ellioti) have sometimes been considered as subspecies of the common paradise kingfisher.[6]
Description
This kingfisher has a red bill, a dark turquoise cap with brighter blue edges, blackish cheeks, and bluish-black upper parts. The under parts are white and the under-wing coverts are blue and white. The central tail feathers are elongated and their base is blue.[7] It is similar in appearance to the buff-breasted paradise kingfisher (Tanysiptera sylvia) apart from the colour of the breast, and in some parts of Papua New Guinea, both birds coexist.[7]
History
The bird is described in Alfred Russel Wallace's The Malay Archipelago (1869).[8]
I also obtained one or two specimens of the fine racquet-tailed kingfisher of
Moluccas, New Guinea, and Northern Australia. About ten species of these birds are now known, all much resembling each other, but yet sufficiently distinguishable in every locality. The Amboynese species, of which a very accurate representation is here given, is one of the largest and handsomest. It is full seventeen inches long to the tips of the tail-feathers; the bill is coral red, the under-surface pure white, the back and wings deep purple, while the shoulders, head and nape, and some spots on the upper part of the back and wings, are pure azure blue. The tail is white, with the feathers narrowly blue-edged, but the narrow part of the long feathers is rich blue. This was an entirely new species, and has been well named after an ocean goddess [a Naiad], by Mr. R. G. Gray.— Wallace[8]
Distribution
The common paradise kingfisher is found in the forested interior of New Guinea and on some of the offshore islands to the north. Its distribution is rather patchy and it mostly occurs below 500 m (1,600 ft) on the mainland and 820 m (2,700 ft) on
Ecology
This species is common and mostly non-migratory, although some birds move out of monsoon rainforest in the dry season. A pair will defend a territory of 0.3 to 0.5 hectares (0.7 to 1.2 acres). The nest is made in an active termite nest in a tree. The termites build a termitarium against the tree trunk and the birds excavate a hole in its earthen wall, which can be as much as 15 cm (6 in) long leading to a 13 cm (5 in) chamber at the end. They usually try several sites before selecting one. A clutch of about five eggs are laid between November and March and both parents care for the young.[6]
The diet consists of such invertebrates as earthworms, grasshoppers, beetles, caterpillars, centipedes and snails, and occasionally lizards. The bird perches upright on a low branch, remaining stationary for long periods, apart from occasionally twisting its head or flicking its tail. On seeing movement below, it swoops to the forest floor to pounce, returning with its prey to the branch. The victim may be dismembered, or subdued by bashing it against the branch. Some insects are plucked off foliage, while earthworms are sought by foraging through the leaf litter and probing the leafmould with its beak.[6]
Status
T. galatea has a very wide range and is reported to be common. The population trend for this bird is thought to be downward as logging takes place in its forest habitat, but the rate of decline is not great enough to cause concern and the International Union for Conservation of Nature has assessed its conservation status as being of "least concern".[1]
