- Risiko rendah
A small forest sparrowhawk that drops from a shaded branch in a single explosive burst. More often glimpsed than identified, leaving only the silence of the songbirds behind it.
- Populasi
- Roughly 40,000-400,000 mature individuals; older estimate ~100,000 total (~67,000 mature).
- Habitat
- Dense evergreen and broadleaf forest, forest edge, and secondary growth from lowlands into hill and lower montane elevations; in the non-breeding season also uses more open woodland, savanna, and cultivated/agricultural land.
- Fakta menarik
- The Besra hunts with a distinctive "flap-flap-glide" flight and uses its short, broad wings and long tail to twist through dense forest vegetation in fast, surprise attacks on prey.
- Sebaran
- Widespread resident breeder across southern and southeastern Asia: the Indian subcontinent (including Himalayan foothills) eastward through mainland Southeast Asia into East Asia (southern China, Taiwan), south through the Malay Peninsula, Sumatra, Java, other Indonesian islands, and the Philippines; roughly ten subspecies recognized.
- Makanan
- Small birds and mammals, lizards, and large insects such as dragonflies, taken in fast surprise attacks from cover in a sparrowhawk-like hunting style.
