Given below are main similarities and differences between birds and reptiles.


  • Both are vertebrates.
  • Both breathe through lungs
  • In general both are oviparous, that is their young ones hatch out of eggs laid by them. However some reptiles are viviparous, that is they directly give birth to young ones.


  • Birds are the only animals that have feathers and wings. But this does not mean that all birds can fly., Or that birds are the only animals that can fly.
  • Reptiles have a dry scaly skin in contrast to birds that have feather covered skins. Most of the reptiles shed their skin several times a year.
  • Birds are warm blooded animals, while reptiles are cold blooded animals.
  • All birds have two hind legs. They also have fore limbs in the form of their wings. The number of limbs or legs in reptiles is variable. Most of the reptiles have four legs, while other may have no legs at all..
  • Birds do not have any teeth. Instead they have a hard beak or bill. In contrast reptiles have teeth.
  • Birds live only on land, although some birds are able to swim in water. Some reptiles live on land while others live in water. Some reptiles live on land as well as water.

First of all find out all the traits/characteristics of each animal.  Then group them in a Venn Diagram.  (Two circles overlapping with a section in the middle which will show how they are similar.)  The sections that do not overlap will show how they are different.  Then you will be able to make a comparison statement/paragraph about hwothey are similar and different.
