Penguins
Airplane designers have been influenced by the study of birds through examining the different qualities of their wings. The strong bones of the birds that are very light help determine the necessary weight restrictions and alloys used in wings. The shape of the wings of birds shows them how to shape airplane wings for maximum lift.
It depends on the mammal. Most common is 4 or 2 legs.
Flight is a phenomenon that has long been a part of the natural world. Birds fly not only by flapping their wings, but by gliding with their wings.
they have 4 wings a top wing and a bottom wing
yes it is. The kiwi's closest relatives were the other New Zealand ratites, the Moa which was another flightless bird.

Other than flying, wings are used to help control body temperature. This is done by flapping them to circulate air when the bird is hot. Or puffing them up to capture pockets of air to warm up the bird in the cold.Some birds use their wings as body language to communicate with other birds. And certain species of birds also use their wings as a display of aggression or dominance.Other species, particularly parakeets and parrots, have been observed using their wings to huddle chicks in order to keep them warm and dry. Click here to see a fascinating and cute picture of a motherly pink-necked green pigeon, which are found in Asia, doing that.
Both have four limbs. A bird's front limbs have been modified into special structures called wings. Similarly, a human's front limbs have been modified into arms. The basic quadrupedal structure is common to nearly all higher vertebrates (even some snakes have indications of vestigal limbs).
Cutting your birds nails and wings is normal and will not hurt them. You bird is just not use to their nails and wing feeling a little different.
