1. Black Guan
An endemic species (lives only in Costa Rica or small surrounding region) resembling a black chicken with a long tail. However, they are much better fliers than chickens and spend a lot of time in trees.
2. Brown Booby
I've always wanted to see a booby (no, I've seen plenty of that kind), and this is the species most commonly spotted from Costa Rica's coast.
3. King Vulture
Ok, for a vulture, you have to admit that this guy is gorgeous. That fleshy thing hanging off its beak is called a caruncle, and is similar to a turkey's wattle.
4. Crested Caracara
I love birds of prey, and I've always wanted to see this badass-looking falcon.
5. Crimson-fronted Parakeet
Another endemic species, this is the most common parakeet in Costa Rica's Central Valley.
6. Scarlet Macaw
This iconic bird of the American tropics uses its strong bill to open large, tough seeds, or remove your finger. After seeing them in movies and zoos, it'd be great to spot that vibrant plumage in the wild.
7. Fiery-throated Hummingbird
Hummingbirds are tiny, jeweled wonders of evolution; able to beat their wings 12-90 times per second (depending on the species). There are more than twice as many species of hummingbirds in Costa Rica as in North America. This species is endemic and embodies all the colors of the rainbow.
8. Purple-throated Mountain-gem
Another beautiful, endemic hummingbird, the male and female could be mistaken for different species.
A pretty, endemic bird, with an awesome zebra-striped tail.
A big reason why birders go to Monteverde, the elusive quetzal is Guatemala's national bird and the name of their currency. A must for any bird list.
11. Blue-crowned Motmot
This bird is very pretty, and also has a cool tail, which it swings like a pendulum.
12. Keel-billed Toucan
Another iconic tropical bird, toucans use their large, dextrous bill to reach tasty fruit.
13. Three-wattled Bellbird
Just look at this guy, who wouldn't want to see this distinctive, endemic, obnoxiously loud bird?
14. Bare-necked Umbrellabird
Another very distinctive, endemic bird, and possibly a winner for best hairdo? I guess it's very difficult to photograph too; Google Images turned up zero good photos of this guy.
15. Orange-collared Manakin
Recognize this one from my blog profile? I'd like to see my mascot in the wild.
16. Clay-colored Robin
Of all the beautiful, colorful birds in Costa Rica, you'd think they'd choose something besides this robin for their national bird. But supposedly it has a beautiful song.
17. Golden-browed Chlorophonia
It's endemic, pretty, cute, and green. What's not to love?
