Asian Openbill -- part of colony

Asian Openbill is a member of the Storks family (Ciconiidae), named for the usually obvious gap between the mandibles. This gap may have evolved for manipulating snails, which are the main food source. The range of the species is primarily the Indian subcontinent and Southeast Asia. Our boat trip in the wetlands of the Bueng Boraphet Non-hunting Area in Nakhon Sawan province, Thailand, took us close to a large breeding colony. This image shows a few of the many nests. (Cormorants also frequent the spot.)
