Genus Thalassornis

White-backed Duck - These birds are well adapted for diving. On occasions they have been observed to stay under water for up to half a minute. They search especially for the bulbs of waterlilies. From danger, they also escape preferentially by diving; hence, the namesake white back is hardly visible in life.
