           Birds are warm-blooded vertebrates that fly. They have two eyes,  a four-chamber heart, feathery wings, and can survive cold, dry, and moist  conditions. Their long, curved wings allow them to migrate and fly. Young birds  cannot fly during the first few weeks of their life, so they depend on their  parents for protection and nourishment. When they begin to develop flight  abilities, they become fledglings, a stage in their life cycle.
           
           All birds begin life in an egg. Eggs vary in size. Some are  smaller than others, but all contain an embryo. Some species lay only one egg,  while others lay several. The Gray Partridge, for example, can lay as many as  20 eggs. After the egg is laid, the parent bird broods it. When the embryo  hatches, it forms into a chick. It has a hard tooth, which frames the beak of  the new bird.
           
           As mentioned earlier all birds start their lives inside an egg.  Depending on the species, eggs can be white or yellow, with a soft shell to  protect the embryo. The size of the egg varies, and some species lay multiple  eggs, such as the Gray Partridge. The egg is brooded by the parent bird, while  the embryo grows inside the shell and turns into a chick. When it is born, it  is named a chick. As the embryo matures, it forms a hard bone structure that  frames the beak of the baby bird. This structure is called an egg tooth, and it  is the only part of the bird's body that is made of bone.
           
           The next stage in the life cycle of a bird is the development of  its adult plumage. The plumage of a bird is the layer of quills covering its  exoskeleton. The young bird has no feathers, so it has a soft, undeveloped  plumage that is replaced after several shedding periods. This is the phase of  development during which the bird is neither fully grown nor explicitly mature.
           
           Once a bird has grown to maturity, it has its own unique  characteristics. It has a distinct appearance, and it is also fully-fledged. It  can fly out of the nest and begin to search for mates. It can lay eggs and  become a parent. This is the beginning of the bird life cycle. Then the adult  is ready to breed and reproduce.
           
           If you  want to learn the basic stages in the life cycle of a bird, hit the start  button in the game above and begin to drag and drop the different stages in  their right positions. Also listen to the audio to hear the names of each part.  Remember to also drag and drop the spellings in their correct positions. This  game is for students studying biology in 2nd, 3rd, 4th, 5th, 6th and 7th  grades. It can be played at home or in the classroom.
