Pelicans ( Undan ) of Malaysia

Pelicans are a genus of large water birds that make up the family Pelecanidae. They are characterised by a long beak and a large throat pouch used for catching prey and draining water from the scooped-up contents before swallowing.

 The 8 living pelican species were traditionally divided into 2 groups, one containing 4 ground-nesters with mainly white adult plumage (Australian, Dalmatian, great white, and American white pelicans), and one containing 4 grey- or brown-plumaged species which nest preferentially either in trees (pink-backed, spot-billed and brown pelicans), or on sea rocks (Peruvian pelican).
