1. Great Hornbill
With a large casque on its beak, the Great Hornbill is one weird-looking bird. The protrusion serves no evident purpose, and scientists believe it likely grew as a result of sexual selection. Whatever the casque is for, the Great Hornbill is a bird you’ll have no trouble recognizing.
Where to find them: Hilly, old-growth forests throughout Vietnam.
2. Snub-Nosed Monkey
To catch a glance of these monkeys, you’ll need to head up into the northern mountains of Vietnam. They live in groups of up to 600 members, splitting up into smaller groups during winter. They are territorial and will use their wide vocal range to scare off anything they consider a threat.
Where to find them: The mountain forests of Northern Vietnam, near the Chinese border.
