Which Bird Is A Mammal? Myth Bust


Most people do not know that there is any bird known as a mammal. Due to this, when you search for a query about which bird is a mammal, you need a satisfactory answer. Many of us said that there is no bird is a mammal. But is it true?

No, it’s not. Kiwi is a bird known as a mammal (but they are not) and we call it an “Honorary Mammal.” All birds have their specific class, “Eve,” but with an appearance of a bird, this tiny creature (Kiwi) has many adaptations that allow us to consider them a mammal. 

We cannot define birds and mammals equally. It is because the history of birds relates to theropods, a group of dinosaurs. On the other hand, mammals appear 50 million years after the evolution of birds. The forefathers of kiwi evolve some adaptations of land mammals for their survival.

These are some reasons that we can consider the kiwi a mammal.

  1. Wings are the central part of the body of a bird. It is because it makes them able to fly. Flying is the main trait of bird species. Aside from this, some birds are not able to fly. Ostriches, penguins, rheas, cassowaries, and emus are some flightless birds. Kiwis are also one of them. They use the land to walk.
  2. Almost all species of birds have a tail in their body, but kiwis have no tails. Compared to other birds, the kiwi’s egg size is more extensive than other birds.
  3. When the chicks of birds are born, they cannot feed themselves. So, they rely on their parents. Compared to them, the offspring of kiwis can feed themselves after just hatching. They are known as mini-adults. This also makes them different from birds.
  4. Most birds have plumage (cluster of feathers), but kiwis have furry skin. It looks like their plumage has more feathers than typical birds.
  5. Around their beak, there are whiskers which are an adaptation of mammals. It also makes them different from birds.
  6. Birds have excellent eyesight, but kiwi needs better eyesight. They are nocturnal creatures and mainly depend on senses other than seeing, which makes them different from birds.
  7. In birds, there is a plate that splits their eye sockets, but in the kiwi case, it is different. It is because they have a nasal cavity which most mammals have.
  8. As they are almost blind, they need senses like smell and touch. They also should be audible. In addition, they have nostrils at the end of their beaks, which is also a distinct adaptation. Due to this different adaptation, they can grab insects and worms without seeing them.
  9. As mammals have bone marrow in their bones. Just like them, kiwis also have marrow bones. Despite this, the bones of birds are hollow.
  10. Body temperature is also different, making them different from birds. They have a body temperature of 37 C, wherever the body temperature of birds remains 38 or 39 C.
  11. Kiwis have strong and fibrous legs. The weight of their legs is 1/3 of their total body weight. On the other hand, birds have very low-weight skeletons, which helps them fly more efficiently.
  12. As badgers (a mammal) can dig holes, kiwis also can dig holes.
  13. A bird female has only one ovary, but a kiwi female has two ovaries, like mammals. Ovulation may occur in another ovary if it makes more than one egg in its clutch.
