Chinese Hwamei
Encyclopedia
The Chinese Hwamei or Melodious Laughingthrush (Leucodioptron canorum, formerly Garrulax canorus) is a passerine
bird
of eastern Asia
in the Old World babbler
family, Timaliidae. The name "Hwamei" comes from the Chinese
画眉 (huà-méi) and means "painted eyebrow" referring to the distinctive marking around the bird's eyes. The species is a popular cagebird because of its attractive song.

Island. The Taiwan Hwamei
(Leucodioptron taewanum) was formerly considered to be a subspecies of the Chinese Hwamei but has recently been split as a separate species. Based on a study of the mitochondrial
cytochrome b
gene
, Li et al. (2006) suggested that the two species diverged about 1.5 million years ago with the two Chinese Hwamei subspecies diverging about 600,000 years ago. The two were formerly placed in the genus
Garrulax with the other laughingthrush
es but have recently been moved to a new genus Leucodioptron.
The Chinese Hwamei was introduced to Taiwan
in large numbers in the 1980s and hybridization with the native Taiwan Hwamei is occurring which may threaten the genetic uniqueness of the latter form.
is mostly reddish-brown with dark steaks on the crown, back and throat. There is a white ring around the eye which extends backwards as a white stripe. The bill
and feet are yellowish. Birds on Hainan
Island (L. c. owstoni) are paler below and more olive-coloured above. The Taiwan Hwamei is greyer and more streaked and lacks the white markings on the head.
The song
is a loud, clear, varied whistling with regular repetition and imitations of other birds. The call is a rasping whistle or rattle.

. In the Hawaiian Islands it was introduced in the early 20th century and now occurs in both native forest and man-made habitats. It is common on Kauai

The breeding season lasts from May to July. A large cup-shaped nest
is built up to two metres above the ground in a tree or bush or amongst undergrowth. Two to five blue or blue-green eggs
are laid.
