マミジロモリツバメ Artamus superciliosus

Chunky bird with broad, triangular wings and short, decurved bill. Male dark gray above, dark orange-brown below, with dark gray face and throat and white eyebrow. Female similar in pattern but less richly colored. Whitish underwings contrast powerfully with dark underparts in flight. Often forages very high up in enormous flocks, sometimes mixed in with Masked Woodswallows.
