Taxonomía

The white-cheeked starling was formerly placed in the genus Sturnus. A molecular phylogenetic study published in 2008 found that the genus was polyphyletic. In the reoganization to create monotypic genera, the white-cheeked starling and the red-billed starling were moved to the resurrected genus Spodiopsar that had been introduced in 1889 by Richard Bowdler Sharpe. The species is monotypic: no subspecies are recognised.

Distribución y hábitat

The breeding range covers central and north-east China, Korea, Japan and south-east Siberia. In winter, birds from colder regions migrate south to southern and eastern China, South Korea, southern Japan, Taiwan and northern Vietnam with vagrants reaching the Philippines, Thailand and Myanmar. There is a record from Homer, Alaska in 1998 which probably arrived with a ship (West 2002).<p>It inhabits woodland, farmland, and open country and has also adapted to parks and gardens in urban areas. It is most common in lowland areas (usually below 700m in Japan).<p>It has a varied diet which includes fruit and insects such as mole crickets.<p>The breeding season lasts from March to July and often two clutches of eggs are laid during that time. The nest is built in a hole in a tree or building or in a nestbox. Four to nine eggs are laid and are incubated for 14 to 15 days. The young birds fledge 13 to 15 days after hatching.
