By: Larry Villalobos and Autumn Rauchwerk When a troop of squirrel monkeys passes near the station it is like watching a band of teenagers. Their antics are of course cute, and they look like they are happy and having fun. Of the four species of monkeys found in Costa Rica, squirrel monkeys are the smallest, weighing about one and a half pounds. This puts them at about the same size as a squirrel. Their fur is a rich orange color, and their faces are unbelievably expressive. These aspects make...

By Larry Villalobos and Autumn Rauchwerk Cuando una tropa de monos ardilla pasa por la estación es como mirando una banda de adolescentes. Sus payasadas, por supuesto, son lindos, y aparecen como si están alegres y disfrutándose. De los cuatro especies de monos que uno se puede encontrar en Costa Rica, los monos ardilla son los más pequeños, con un peso de aproximadamente 1,5 libras, casi el mismo tamaño de una ardilla. Su pelaje es del color naranja y sus caritas son muy expresivas. Con estas características, son irresistibles...

By Juan Carlos Cruz Jaguars are very charismatic creatures, and for indigenous people and ancient civilizations, were considered symbols of power, majesty and wisdom. While that symbolism still holds true, we now also recognize their intrinsic value for maintaining biodiversity in the forests. They are on the top of the food chain and therefore the health of their population affects all subsequent levels. In the absence of Jaguars, breakdowns occur in the ecosystem such as increases of populations of herbivores, decreases in population of some species of plants (eaten by herbivores) and loss of other species of birds, insects and reptiles that depend on those plants. The presence of Jaguars in a region is an indicator of the health and integrity of the forest since they are the most sensitive species of all large cats to exploitation and habitat alteration. Accordingly, they are also known as “health indicator species.”

As some of you may know from following our Facebook and Twitter posts, Manuel Sanchez Mendoza, our Research Assistant and Sea Turtle Conservation Program Field Coordinator, has one heck of a talented eye for photographing wildlife. As an Osa native, born and raised in the peninsula, Manuel has always been fascinated with wildlife, and although he has no formal training in photography, we like to think he has a natural-born knack for it. The past few weeks in particular have been very successful for Manuel and his camera, and we at Osa Conservation are excited to share his sightings with you! All of these photos were taken at or around our Piro Biological Center.

In order to create public access stations for environmental education purposes, Osa Conservation recently built and inaugurated a 2.5-mile interpretive trail. In this easy journey, adventurers will find 23 stations labeled to help them understand and interpret the ecosystems, species and ecological associations that cross the path, which is a representation of the biological richness of the Osa Peninsula.

Las Lapas Rojas (Ara macao), son una especie en grave peligro de extinción. En Costa Rica existen solamente dos poblaciones viables de Lapas Rojas, la más grande de las cuales se encuentra en la Península de Osa. Esta población se estima entre 800 y 1200 individuos (Dear et al 2010). Dicha población fue eliminada casi por completo debido a la tala indiscriminada de arboles para madera y agricultura, la casería para consumo, y  el comercio ilegal de estas aves como mascota. Durante las ultimas dos décadas, la tala comercial y la cacería de aves ha disminuido significativamente, y la población de Lapas de la Península de Osa se ha incrementado rápidamente. Sin embargo, la perdida de cavidades naturales usadas como nidos por estos animales ha limitado grandemente la recuperación de sus poblaciones. Un estudio realizado en los últimos anos recomienda usar un sistema de conservación de largo plazo que combine educación ambiental en las escuelas locales, involucramiento de las comunidades, y penalidades mas estrictas para los cazadores y destructores del hábitat de la Lapa Roja (Guittar et al 2008).
