Northern Tamandua, Corcovado National Park, Costa Rica
Tamanduas are a genus of anteater. There are two distinct species, the southern and the northern tamandua. The northern live in the forests of Costa Rica. This particular guy was having a good old time sucking up an army of ants that were crawling on that tree.
