A common day in the life of a spider monkey consists of a family group of 20 to 40 individuals whom separate into smaller groups of 3 to 8 that forage during the day,...

Written by: Pilar Bernal Translated & Edited by: Florencia Franzini On April 23rd I was invited to participate in the 10th annual Biodiversity Symposium of the Osa Peninsula, sponsored by the Conservation Area of Osa (ACOSA), in order to promote the exchange of ideas and give rise to awareness of the newly marked biodiversity zones, to a sensitive and environmentally active public. The previous years talks in the symposium had included mainly land issue topics focusing on trees, primates, bats, and aves, but this year we kick-started the conversations with...

by Juan Carlos Cruz Díaz, Science Program Manager Mammals are a very important element in ecosystems, and the rainforest is no exception. Wildcats as the top predators in an ecosystem provide control for the lower levels of the food web such as herbivorous animals, which in turn control biomass production. Everything is in perfect balance, so if a top predator is missing from the ecosystem, herbivores will increase in number and that will tremendously affect the biomass production, potentially leading to ecosystem collapse. For this reason it is highly important...

By having a solid environmental education and outreach program, we can promote long term appreciation, awareness and respect for our environment. For this reason, a few months ago, as part of the Science Program at Osa Conservation, we started delivering a series of talks to locals, schools and tourists in...

Photo by Alan Dahl[/caption]   Fall is fast approaching, and the change of seasons signals something particularly exciting for the Osa Peninsula – the return of migrating birds! The Osa is home to almost 500 resident bird species and many more who migrate to the peninsula from boreal forests in the US and Canada. Now in the middle of September, the migratory bird season is well under way, with species such as the Golden-winged warbler, Olive-Sided Flycatcher, and the Baltimore...

Home to dozens of marine species, including the four turtles known to nest in the Osa, two species of dolphins, and even Whale Sharks, Gulfo Dulce is an incredible addition to the biodiverse rainforest that surrounds it (Bessesen, 2011). An inlet, protected from the rough waters of the Pacific, and with waters as deep as 300 meters, it is the perfect birthing spot for many animals, especially the majestic Humpback Whale (Golfo Dulce). This calm water paradise is also a beautiful and popular boating spot for locals and tourists, and...

[gallery columns="2"] By Hansel Herrera Vargas The 2013 volunteer season began in the month of July and it seems good times are on their way… With so many volunteers on the calendar, dozens of sea turtles arriving on our beaches, and the hard work of the field assistants and interns, Osa Conservation is opening its doors and is beginning the 2013 volunteer season.  The first volunteers arrived last Friday and during a patrol had the good fortune of finding one of the most precious visitors of the Osa Peninsula.  On Sunday night...

  By Madeline Crocker Neotropical migratory birds inspired an international agreement between Costa Rica and the United States last month.  These birds migrate back and forth between the United States and Canada and Central and South America.  They carry out important reproductive functions in the north and migrate south during the northern winter months, where food is more plentiful. The dual importance of both regions in the lives of these birds brought about a "sister parks" partnership, signed between Costa Rica's National System of Conservation Areas (SINAC), the St. Croix National...

  By Gloriana Chaverri, Ph.D. Professor Universidad de Costa Rica   We have all heard about the different ways of attracting birds to our backyard. For example, people hang ripe bananas, provide plants with colorful flowers that are visited by hummingbirds, or place feeders with seeds. However, few people know how to attract bats into their backyards, and fewer yet would wish to given their bad reputation as blood-sucking elusive creatures. Osa Conservation, together with Fundación Universidad de Golfito, is using bat boxes to lure fruit-eating bats into areas that are in need...
