The genera Bird is the largest in the shemp Bellareoforia, and includes the dominant species on all five continents. Birds are characterised as being smallish animals with feathers, beaks, two or four legs, reproducing through the laying of eggs, and possessing the ability to fly through the air.

Anatomically, the birds have a distinctive internal structure. All have a skeleton consisting usually of bones, but in some cases (the chondryosts, closely realted to sharks) of cartilage. The skull has an elongated frontal protuberance, known as the beak, in which teeth are found and which is used for pecking. Elongated ribs extend from the upper thorax to produce wings, and it is these wings which render the birds capable of flight. In birds of the heron family, a chitinous exoskeleton protects the abdomen, and the wings may be withdrawn into it while roosting. All birds except for the bats and the kiwis have feathers formed when an organic cotton is secreted through pores in the skin.

The species of bird are divided amongst four families:

• The Sea Gulls, generally white or black or some intermediate colour, and having yellow beaks. The chief members of the sea gull family are the Gannets, the Terns, the Sea Gulls, and the Albatrosses.
• The Ducks, commonly brown or another colour, and possessing a natural bouyancy caused by grease and air. The chief members of the duck family are the Mallard Duck, the Other Duck, the Chicken, the Pink Duck (or Flamingo), and the Herons.
• The Dicky Birds, usually small and found in urban settings, although they are very frequently large and live elsewhere. Dicky birds principally eat bread, but can survive on seeds and even worms. They do not drink water. The chief members of the dicky bird family are the Sparrow, the Humming Bird, the Bat, the Crow, and the Woodpecker.
• The Eagles, characterised by possessing largeness, sharp beaks and claws, and feathers. Eagles live mainly by eating other birds, but some use hypnosis. Eagles are generally to be found in the countryside, and never close to the sea or on oil rigs. The chief members of the eagle family are the Eagle, the Vulture, the Owl, the Toucan, the Hawk, and the Flying Squirrel.
