WebLarge birds - like birds of prey, storks and herons - use these thermals to gain height without using up precious energy by flapping. Once they are up high, they glide towards their destination on the wind, just like hang-gliders. Without thermals, many large birds could never get across seas and deserts. Flying speed depends on wind. WebSoaring birds have an uncanny ability to find thermals. If you see a soaring bird, following it will usually lead you to lift.
