Not all bones in a bird's body are hollow, though, and the number of hollow bones varies among species. Large gliding and soaring birds tend to have more, while diving birds have less. Penguins, loons, and puffins don't have any hollow bones. It's thought that solid bones make it easier for these birds to dive.

Birds have feathers and hollow bones, which separates them from all other living animals. They also lay hard-shelled eggs (reptile eggs have soft, leathery shells). Most birds can fly while most other animals, besides insects, cannot, and their wing is basically their arm, with feathers creating the flight surfaces.
