About Geokichla spiloptera (Blyth, 1847)
This medium-sized thrush, Geokichla spiloptera, ranges 21 to 27 cm (8.3 to 10.6 in) in total length and averages 70 g (2.5 oz) in weight. Adult birds have light brown upper plumage, with a double wing bar formed of white spots. Their pale face is marked with two dark bars, and their white underparts have heavy spotting. Adult bills are black, and their legs are yellow. The song of this species is a rich, varied whistling. Juvenile birds have buff streaking on the upperparts; their face and underparts are light brown with heavy streaking. This is an uncommon species that breeds in hill rainforests, and less frequently in drier woodlands, at altitudes between 500 and 2000 m. It uses similar habitat for wintering, though wintering ranges also include less heavily wooded areas, and are generally found at 750 to 1500 m in altitude. The spot-winged thrush is typically solitary and quite secretive, especially within the dense undergrowth and bamboo clumps it prefers. It builds loose cup-shaped nests lined with vegetation, placed in tree forks. Females lay 2 to 3 buff or bluish-green eggs per clutch, and the species raises two broods each year. Spot-winged thrushes are omnivorous, though they consume far more insects than fruit, and they forage for food on the ground.
