Lesson 9 - Vertebrates: Birds

Introduction

Birds are warm-blooded animals. They have been on Earth for many millions of years!  Birds have a lot in common with reptiles, such as turtles, crocodiles, and lizards. Scientists think that birds and reptiles are closely related and have many shared traits, such as laying eggs. Scientists also know that birds have some very different traits from their relatives, such as feathers instead of scales (though most birds have reptile-like scales on their legs and feet), pointed beaks, and wings. Most birds have hollow bones, unlike reptiles. There are around 10,000 different known species of birds today. They live on all seven continents and have adapted to live in every climate!
