Hornbill

---

The enlarged bills of
toucans and hornbills
are ornate, pigmented,
and used in mating
displays, yet the two
birds are not related.
Toucans live in the
American tropics;
hornbills come from
Africa. That similar
birds, like toucans
and hornbills, exist
in different forests
means that each is
a product of its own
environment.
