ack Ewing’s most recent book – Monkeys are Made of Mangos: Colorful, Captivating Costa Rica – is a collection of 40 compelling short essays told in the first person by Ewing, a cattle rancher turned naturalist and environmentalist.

It’s natural that when we see a small, helpless animal, our first instinct is to help it. However, when it comes to wild animals, intervening—despite good intentions—can actually do more harm than good.

Es normal que si vemos un animal pequeño e indefenso nuestro primer instinto sea ayudarlo, sin embargo, en el caso de animales silvestre esto a la larga puede ser perjudicial para el animal, por más que nuestras intenciones sean buenas.

Sloths are peaceful, tree-dwelling icons of Costa Rica, and spotting one in the wild is a dream for many of us. But as tourism grows, so does our responsibility to ensure these gentle animals are protected, not exploited.

by Maritere Mendoza González On June 27, 2025, a juvenile white-faced capuchin monkey (Cebus capucinus) was found unconscious on the streets of Manuel Antonio, Costa Rica. It was discovered by a group of girls who were alarmed by their pet's constant barking. Upon investigating, they noticed the unresponsive monkey. Concerned for its well-being, this encounter prompted the girls to transport the animal to Kids Saving the Rainforest (KSTR) so it would receive the appropriate c

In and around Manuel Antonio National Park, spotting a sloth is always a memorable experience. Whether they’re curled up in the treetops or slowly making their way from branch to branch, these iconic animals never fail to capture attention!

At Hacienda Barú National Wildlife Refuge  there is a trail called the “caiman trail” because one of our guides sighted a caiman there in  March of 2016.  Late in the dry season, competition for possession of the few puddles that remain in the lowlands is so intense that caimans and otters are sometimes driven to walk great distances in search of w

A World Class Escape Artist Back in April of 2016 an octopus named “Inky” escaped his tank in the National Aquarium of New Zealand in Napier and made it out to sea, and freedom. This is perhaps one of the greatest stories of forging one’s independence there ever was.  The breakout, which has captured the imagination of New Zealanders and made headlines around the world, apparently began when Inky slipped through a small gap at the top of his tank, likely left open during rou

Una Artista de Escape de Clase Mundial En abril de 2016, un pulpo llamado "Inky" escapó de su tanque en el Acuario Nacional de Nueva Zelanda en Napier y logró llegar al mar, en busca de la libertad. Esta es quizás una de las mejores historias de independencia que jamás haya existido.

¿Alguna vez has visto un caimán en la ladera de una montaña en un bosque primario a más de un kilómetro del agua más cercana? En el Refugio Nacional de Vida Silvestre Hacienda Barú hay un sendero llamado "sendero del caimán" porque uno de nuestros guías avistó uno allí en marzo de 2016.  A finales de la temporada seca, la competencia por los pocos charcos que quedan en las tierras bajas es tan intensa que los caimanes y las nutrias a veces se ven obligados a caminar grandes d

“I never imagined any of this. It’s awesome. You know what? You should write this all down; all the same stuff you just told me. It’d make a great article. Lots of people out there would love to learn about this stuff. I’m sure you could get it published.”

Based in Manuel Antonio, The Sloth Institute is dedicated to enhancing and expanding the welfare and conservation of sloths in Costa Rica. These gentle, quiet creatures are iconic to our rainforests, but they face growing threats that require informed, science-based, and community-driven solutions.

In February 2025 we received an emergency call reporting a howler monkey found on the ground. This situation was highly unusual, as howler monkeys are rarely seen on the ground, much less in a resting position. This species is known for spending most of its time in the treetops, where they feel safest and feed on leaves, which make up their exclusive diet.
