Royal Tern at sunset, Tortugeuro River

In the Tortugeuro National Park on the Caribbean coast of Costa Rica. Along with Blue Heron, Black Vulture, other wonderful birds.
Image quality lower than I'd wish. I'm having to re-photograph from the view screen of the EOS50D with the IPhone. As howler monkeys earn their name outside the cabin...
Off at 0600 tomorrow for more river exploring. Magic place.
