The Asian Openbill is certainly a distinctive looking bird - the namesake beak is unique to the family - a gap between the two mandibles gives a distinctive profile and is believed to be used to help them feed on aquatic snails - their main prey source.  They are fairly common within their range, and near appropriate habitat and in Prek Toal they proved to be abundant with hundreds seen.
