Blue-winged Kookaburra

The blue-winged kookaburra (Dacelo leachii) is a large species of kingfisher native to northern Australia and southern New Guinea. Measuring around 40 cm (16 in), it is slightly smaller than the more familiar laughing kookaburra. It has cream-coloured upper- and underparts barred with brownish markings. It has blue wings and brown shoulders and blue rump. It is sexually dimorphic, with a blue tail in the male, and a rufous tail with blackish bars in the female. == Taxonomy == The blue-winged kookaburra was first collected by Sir Joseph Banks in 1770, but was initially overlooked and confused with the laughing kookaburra, and was finally officially described by Nicholas Aylward Vigors and Thomas Horsfield in 1826, its specific name commemorating British zoologist William Elford Leach. It is one of four members of the genus Dacelo which are commonly known as kookaburras. Alternative common names include barking or howling jackass, or Leach's kookaburra. The number of subspecies is unclear - with four recognised by most authorities, although others have proposed that the three Australian subspecies gradually change across Australia and should be treated as one. D. l. leachii is the nominate subspecies, found from Brisbane to Broome. D. l. cervina is found…
