Some birds can not only fly and swim but also dive underwater to find food. The first diving birds were Hesperornises, which lived in the Cretaceous period. There are many birds today that have preserved this skill. The most common, of course, are ducks and their entire duck family. Some ducks can dive to great depths and stay underwater for a significant amount of time.
