Difference and similarities of birds reptils and mammals?
SIMILARITIES. Birds, reptiles, and mammals are all a part of the animal kingdom! (OH MY GOSH!) They all need the same things- food, water, vitamins, nutrients, and things of the such. They are all multi-cellular, eukaryotic organisms. They all have the ability to mate and raise/have offspring. These three also all have similar body parts, and body functions. DIFFERENCES. Mammals give birth to live offspring- birds and some reptiles don't and lay eggs. Birds have the ability of flight- mammals and most reptiles do not. Reptiles are covered in scales or some other form of rough 'coat'- birds have feathers (though some like the Cassowary have some rough and slightly scaly napes and such), and mammals have fur and things of the such. Reptiles and most birds are warm blooded- mammals are cold blooded. Hope it helped! :D ~AP Wulf

During winter they need more food to burn for respiration and therefore are more active because they search for food all the time.
