A small diving bird, also known as a grebe, especially the dabchick or other small grebe species.
From Middle Dutch 'ducdopper' or similar Germanic roots, combining words meaning 'diving' and 'dapper' (small person). The term evolved to describe the bird's diving behavior.
Didappers are incredibly cute water birds that can dive faster than they can fly—they're so specialized for diving that their legs are positioned so far back they're nearly helpless on land.
