Difference Between Animals And Birds


Biologically, an animal is a living thing that is not a human being or plant. A bird is classified in kingdom animalia meaning it is also an animal. Despite the fact that birds are animals, they have unique anatomic and physiological characteristics that distinguish them from the rest of the animals. The main evident differences between animals and birds include:

  1. Possession of a beak

A beak is an external anatomical structure found in birds. Most animals have teeth, strong jaws and paws for attacking their prey. On the other hand, birds have beaks which they use for probing for food, killing preys, eating, grooming and also to feed their young ones. The beak is a unique identification of birds from other animals.

  1. Skeletal structure

Most animals have their skeletons adapted to movement on the surface for example; walking is dominant. However the case, birds have their skeletons modified for flight. Most birds have lightweight skeletons and their bones lack bone marrow (hollow bones). Unlike other animals, birds have the two clavicles fused forming the furcula or bone-wish which is both flexible and strong enough to support the shoulder girdle during flapping. The many fused bones in birds including the collar bone and the bone-wish make the skeleton flexible for flight. Birds also have their sternums larger relative to the other body parts. The large sternum provides sturdy attachment points of wing muscles. For this reason, birds tend to be different from other animals.

  1. Pneumatic characteristic

All chordatas (animals that have a backbone), apart from birds, have bone marrow within their bones. Birds have bone cavities that are filled with air in place of the bone marrow. These cavities connect with the lungs of the respiratory system. This unique characteristic enables birds, unlike majority of the animals, to be airborne(able to fly) despite the gravitational effect.

  1. Presence of air sacs

It is biologically proven that from all other animals, it is only birds that do not possess a diaphragm. In place of the diaphragm, birds have air sacs. Air sacs are spaces within the bird where there is constant presence of air. Air is moved in and out of the bird’s respiratory system through pressure changes in the air sacs. The air sacs also extend into some bone cavities and this makes the respiratory system of the birds more efficient. Air sacs also help to keep birds cool by expelling heat; this is quite useful because birds do not sweat.

  1. Possession of feathers

Other groups of animals have their whole bodies covered fur or scales. Birds stand out to be different or unique from the rest of the animals in that; it is now proven that birds are the only living creatures that have feathers. Birds have two types of flight feathers found on the wings: thrust-producing feathers at the tip of the wing and lift providing secondary feathers. Not only flying, birds use their feathers for different purposes such as: regulating body temperatures, camouflaging, attracting mates, territorial dominance among others.

  1. Possession of wings

Animals have their forelimbs adapted differently depending on their environment. It is evident that most of the animals have their forelimbs adapted to walking. In spite of that, birds have their forelimbs adapted to flying. The modified forelimbs in birds are called wings. Birds use the wings primarily to fly though they also use them to regulate the body temperatures. Not all animals that have wings but all birds have wings.

It can be generally concluded that birds are quite different when compared with other animals.

  1. Hi!
    Just to inquire about the fact that man, too, is a mammalian and would to be included among the the other mammalians, no? To not define him as an animal is misleading, don’t you think?

    • Yes, I learned in school that Man is an animal species. Of course, I learned this back in early science class when they did definitions of species. This was back in 1966 and 1967. In today’s world Human has become more than what it is. Somehow we no longer place in Animal kingdom but yet they have not removed us from the Mammal kingdom. What the purpose of this misleading thought process is far beyond my reaches unless we are simply talking about ego. Thanks for posting. Paul Griffith.

      • Where are your sources for this? If a bird and monkey are both animals, humans must also be animals for we have more in common with a monkey than a bird does.

    • We are still considered mammals and mammals are a species of Animal.

    • That’s a good question, that I thought I had an answer to,(well from my view) but as I’ve mulled your words over I find myself saying, huh, that’s a good question. Because we are mammals and an animal is a mammal…..i guess it breaks down to breaking it down, catagories.

  2. God created man separately from the animals, and is the only creature made in the image of God.

    • In the scientific scheme of life form classification, man and woman are part of the animal kingdom, along with all other animals. Since we are not using the Bible as the basis for this scientific classification system, we must acknowledge that it is a sacred text with ancient allegorical stories that seek to make God known to mankind, not to be used as a scientific text.

      We can correlate the stories in the Bible to the scientific knowledge we have discovered and recorded, but some statements in the Bible will never be able to be scientifically proven, such as the image of God. This is the foundation of faith — believing in things we cannot see.

      What characteristic does “the nature of God” capture? His ability to reason? His ability to stand upright when walking? His ability to show compassion, justice, and mercy to His creations? These may be good approximations, but they also originate as thoughts of mankind about God, or mankind’s images/imaginations of God. We must be careful to not create God in our own image, yet we must continually seek to know God more, in personal and intimate ways.

  3. Well I think this is a good site to find out how birds do wonderful things and people can think what they want. But Birds have very beautiful and a wonderful creation of God. They did not just evolve. Thank you for the understanding of Birds. What a marvelous creature.
