The birdlife of Costa Rica is justly famous, and we enjoyed wonderful views of many exotic avian delights, including 25 species of hummingbird (half of the country’s species), toucans, parrots, trogons, kingfishers, motmots and tanagers. Casting our eyes downwards we found colourful plants, poison dart frogs, lizards and even a tiny bright yellow Eyelash Pit Viper, curled up discreetly on a twig, watching us as we walked past.
