A brids' bones are hollow
They have feathers
They have beaks
Feathers, hollow bones and beaks.
Feathers, hollow bones, and beaks.
A beak, claws and wings.
They simply have a spine
their feathers
Vertebrate means spine, backbone. Hummingbirds, like all birds, have a backbone, which makes them vertebrates.
Hair and milk.
A bird has to have feathers, hollow bones, and be warm-blooded. So if a bird has those characteristics it is a bird.Lay eggs and birds are Vertebrates.
Like ALL birds, ducks have a backbone, which makes them vertebrates.
No. Chickens are birds, which is a different group of vertebrates from mammals. Birds lay eggs, while most mammals give birth to live offspring. The only exceptions to this are the platypus and echidna, which are monotremes, or egg-laying mammals. No. Chickens are birds, which is a different group of vertebrates from mammals.
Yes, an emu is a vertebrate as are all other birds. They have an internal skeleton and a backbone which makes them vertebrates. All mammals, reptiles, amphibians and fish (true fish) are also vertebrates.
Because they have a spine makes them vertebrates.
yes they do they have a back bone right so they are vertebrates.
The most body covering of a bird is the beak.
Echidnas are different as, like platypuses, they are egg-laying mammals. This group of vertebrates, known as the monotremes, is unique: their method of reproduction is laying eggs, yet they nurture their young on mothers' milk. Apart from producing milk to feed their young, there are other differences: they do not fit with egg-laying reptiles as echidnas are warm-blooded; nor do they fit with egg-laying birds because all birds have feathers, and echidnas, like other mammals, have hair/fur.
Yes. Vertebrates are animals having backbones. Since ducks, like all birds, have backbones, they are vertebrates. other vertebrates include all mammals, reptiles, fish, and amphibians (such as frogs).
Yes, elephants have a spine and skeletal structure. This makes them vertebrates.
