I saw this bird to-day, 31-5-2020 at the back of our house in Bangkok's suburbs
Asian Openbill uses warm airstreams for rising in the air, and flies high in the sky. Then, it glides to destination.
Landing is spectacular. Asian Openbill drops from the air as a parachute, with dangling legs, and lands.
