Editor’s Note

In this issue of CC Kids, we meet Anusha Shankar and learn about her work studying hummingbirds at high altitude, on top of a 3000m plateau in Ecuador. We are usually taught that some animals, like reptiles, are cold-blooded; while others, like mammals and birds, are warm-blooded. But these hummingbirds, it seems, can be both. Anusha Shankar is investigating how this could help these unusual birds to fuel their high-speed lifestyles.
