コズアカチャイロチメドリ Malacopteron cinereum

Small, dull, brownish babbler. Pale underparts. Faintly scaled crown is orangish and sets it apart from the dark-crowned but otherwise fairly similar Sooty-capped Babbler. Birds north of the Malay Peninsula and southern Thailand have a bicolored crown, with chestnut on the front half and dark on the back. Inhabits lowland and foothill forests, often in wet areas. Forages in noisy flocks, giving rapid-fire series of ticking notes.
