The dodo bird (Raphus cuculatus) is an extinct bird species in the pigeon family of the pigeon order. The body shape is comparable to that of a swan, and there are also obvious sexual dimorphism. Body length 70-90 centimeters, weight 17-28 kilograms. It is a large bird with a plump body, covered with soft gray feathers, which are brown or gray in color. The female bird has lighter fur than the male bird. There is a white feather on the tail. Their wings are too small and weak to lift the Dodo off the ground. Because they cannot fly, the female bird lays one egg at a time, which is co hatched by the female and male birds. Eating fruits and seeds.
