In knowing a bit about birds, I can tell this bird is a woodpecker. That led me toward the ID quite easily, even without knowledge of Costa Rican species. See the link I provided to find it. Perhaps you could verify that this website has the species named correctly, as I only spend a few seconds on this.

Here is a link that might be useful: http://www.costaricabirdingtours.com/toucans.html

Thanks for the link TMFF, I see it's a Chestnut-colored Woodpecker.
