Birdfinding.info   Uncommon, local, shy, and difficult to find across most of its large range.  It also appears to be somewhat nomadic, appearing at a site for a few weeks, months, or years, then disappearing.  A few sites where it seems to occur consistently include: the Bengal Florican Reserve in central Cambodia; the Chuping Planation in Perlis, Malaysia; the Bislig Airport on Mindanao, Philippines; the Numundo Ranch on New Britain; and in Australia at Lake Samsonvale near Brisbane, Limeburners Creek Nature Reserve near Port Macquarie, and Hexham Swamp Nature Reserve near Newcastle, New South Wales.

King Quail

Synoicus chinensis

Southern Asia to Australia, where it is widespread, but declining and now absent from large portions of its former range.

Occurs in various grassy habitats, generally favoring damp areas.  Mainly in lowlands, but locally up to 2,000 m elevation.

In southern Asia, patchily distributed from eastern India (West Bengal and Assam) and Bangladesh east to southernmost China (Guangxi), and south through Indochina to Singapore.  Also on Sri Lanka and very locally or sporadically in southwestern India (coastal Karnataka and Kerala).

Formerly recorded much farther west in India (to Haryana and Gujarat) and east in China (to Fujian) and to southwestern Taiwan.

Still widely distributed across the Philippines, Indonesia, New Guinea, and New Britain, but apparently localized or sporadic on many of these islands.

In Australia, it occurs in three regions: (1) the Kimberleys and northern Northern Territory; (2) the coastal lowlands from Queensland to central New South Wales; and (3) the central coastal lowlands of Victoria, where reportedly introduced.

Introduced populations are established on Réunion and Guam—and formerly also on Mauritius.

Identification

The smallest of all quails: sparrow-sized and plump.

Male is extensively grayish-blue (sometimes appears vivid blue), with brown shading and black spots on the upperparts, and largely chestnut from the mid-breast to the vent.

Has a striking and complex black-and-white pattern on the throat.

Female’s plumage is cryptically mottled with brown, buff, black, and white.  The head is typically a warm orangey shade of buff, and the middle of the breast and belly are mostly unmarked and whitish.

The female’s most distinctive feature is well-defined blackish barring on the chest, sides, flanks, and vent.

In flight, the female’s wings appear uniform brown—which can distinguish it from some similar species that sometimes occur with it.

Voice.  Male’s typical advertising call is a whistled ti-tu!: Sometimes gives a three-syllable version, ti-ti-tu!:

Notes

Polytypic species consisting of ten recognized subspecies.  Sometimes considered conspecific with the Blue Quail (S. adansonii) of Africa—although they are obviously close relatives, the plumage differences are pronounced and consistent, so this treatment seems incorrect.

Quail of Many Names.  The King Quail is plagued by nomenclatural ambiguity, as it has five English names and three scientific names in widespread use.  Besides King, it is sometimes called Blue-breasted, Asian Blue, Chinese Painted (mainly among aviculturists), or simply Blue (when lumped with its African relative).  Besides Synoicus, it has also been placed in the genera Coturnix and Excalfactoria.

The name King Quail has the virtues of tradition, dignity, and irony to recommend it.  The male is truly regal in plumage, even if minuscule in stature.  The interests of individuation and identity seem to support continued use of the name King, particularly given that the main alternatives (Blue-breasted and Asian Blue) are somewhat inaccurate—as King and its African counterpart both have varying amounts of blue and chestnut on the breast (so “Blue-breasted” is misleading), and King’s range extends far beyond Asia into Australasia (so “Asian Blue” is not quite right).
