A Project Guide to Reptiles and Birds

by Colleen Kessler

There are over 10,000 species of birds and about 9,000 species of reptiles in the world. Both of these animal groups are wonderfully diverse from the flighted to the flightless and the legged to the legless. Scientists have long debated the relationship between birds and reptiles. Whether or not birds and reptiles are truly related, everyone can agree that there are some physical similarities between the species, from the eggs they both lay to the scales that can be found on their bodies. But what about the differences? Birds have feathers and are warm-blooded. Reptiles slither, crawl, and creep and are cold-blooded. Scientists study these similarities and differences by observing and experimenting, and now you can too. Whether you try the experiments and activities in this book for fun or for a science fair project, you ll get an up-close and personal view of these two incredible types of animals. Are they related? You be the judge!
