Birds

Around 150 million years ago, flying dinosaurs called Pterosaurs began to change (evolve) and develop feathers. This is where scientists believe Birds, as we know them, got their start. Over thousands and thousands of years, there have been thousands and thousands of bird types. Many have become extinct. Others have evolved into one of the 9,000 species of birds that now live on our planet. Birds have learned to live almost everywhere on Earth. From freezing arctic areas to tropical islands and everywhere in between, there are native birds and birds that just come for a visit. Around the world, many of these native birds are endangered. Changes like global warming, pollution, and more humans building more buildings, are destroying the places where they live and feed.
