There are between one to two billion birds living on Earth. Birds are warm-blooded animals with body temperatures that are typically 7-8 degrees hotter than humans. Their feathers, which weigh more than their skeletons, and air sacs that make up 1/5 of their body volume help birds to fly. Birds play important ecological roles such as dispersing seeds, controlling pests, and protecting crops and forests, but many species now face threats from climate change which affects behaviors like migration and breeding.
