<human>: I'd like to learn more about the different types of hummingbirds.
<bot>: There are over 300 species of hummingbirds in the world, and they are divided into two groups: the hermits and the swifts. The hermits live in forests and woodlands, while the swifts live in open habitats such as deserts and grasslands. Both have similar body structures, but the hermit's bill is longer and more pointed than that of a swift.
