makes them better streamlined i would guess
Hollow bones in birds are an adaptation for flight because they reduce the overall weight of the bird, making it easier for them to take off and stay airborne. The air-filled cavities within the bones also provide structural strength and help to support the stresses of flying.

All birds have wings. It's just that some of them are useless for flight. The New Zealand kiwi certainly has wings, though it appears to have none. The wings are small and rudimentary, hidden under the kiwis' hairy feathers, but certainly present. The kiwi is a member of the ratite family, a family of birds characterised for being flightless.
Recent discoveries suggest that the earliest birds descended from a small dinosaur known as Archaeopteryx, which developed feathers. Possibly to keep warm.Birds all have feathers, and their young (as the dinosaurs before them) hatch from eggs. The flying birds have hollow bones to reduce weight, but most ground -dwelling flightless birds have more conventional bones. Birds mostly care for their hatchlings, apart from exceptions such as the Cuckoo family.In general the flightless birds such as Kiwi, Ostrich Emu, etc lack a keel bone in their chest to which flight muscles would otherwise attach. This family probably never had flight, but that is subject of dispute.
Yes, birds are eukaryotic organisms. They have cells that contain a nucleus and other membrane-bound organelles. This distinguishes them from prokaryotic organisms, such as bacteria, which lack a defined nucleus.

No, penguins do not have teeth. Instead of teeth, they have sharp, serrated edges on their beaks that help them grip and hold onto slippery prey like fish and squid. This adaptation allows them to catch and consume their food effectively, even though they lack traditional teeth.
The scientific name for flightless birds is ratites. This group includes birds like ostriches, emus, rheas, kiwis, and cassowaries. Ratites are characterized by their lack of keel on the sternum bone, which is necessary for flight muscle attachment.
limiting factor
If your teeth keep chipping off, it could be a lack of calcium in your diet. Other possible reasons could be decay or lack of other nutrients in the body.

The gizzard is a muscular organ found in birds that helps with mechanical digestion. It is tough and rough due to the thick muscular walls that grind and break down food particles. This muscular action helps birds to effectively digest their food since they lack teeth for chewing.
lack of calcium in your body causes white stripes on teeth and nails.
When you can no longer nomm dem burdz, you haez a lack ov calcium.

Soft teeth can be a genetic factor and a lack of Calcium. Speak to your dentist so you can take care of your teeth and gums to the best of your ability.
