The
Chinese hwamei or melodious laughingthrush (Garrulax canorus) is a
passerine bird of eastern Asia in the Leiothrichidae family. 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.
It
has two subspecies: G. c. canorus, native to mainland Asia, and G. c.
owstoni of Hainan 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
laughingthrushes 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.
It
is 21 to 25 cm long with broad, rounded wings and a fan-shaped tail.
The plumage 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.
Distribution and habitat
The
nominate subspecies G. c. canorus occurs across south-eastern and
central China and in northern and central Vietnam and Laos. The race L.
c. owstoni is found on Hainan.
G.
c. canorus has been introduced to Taiwan, Singapore, Japan and Hawaii.
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, Maui and Hawaii Island but less so on Oahu and Molokai.
The
bird inhabits scrubland, open woodland, secondary forest, parks and
gardens up to 1800 metres above sea level. It is common in much of its
range and is not considered a threatened species.
Behaviour
It
is a skulking bird which is often very difficult to see. It typically
feeds on the ground among leaf litter, foraging for insects and fruit.
It usually occurs in pairs or in small groups.
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.
