Birds, Land Conservation and Forest Restoration / 07.12.2012

The Scarlet Macaw (Ara macao) is a species in danger of extinction. In Costa Rica, there are only two healthy populations of scarlet macaws, the largest of which is located on the Osa Peninsula. This population is estimated to be between 800 and 1200 individuals (Dear et al 2010). This population was almost completely eliminated due to the illegal removal of trees for timber and agriculture, hunting for food, and illegal trade of Macaws as pets. During the last two decades, commercial logging and hunting of birds has decreased significantly, and the population of Macaws of the Osa Peninsula has increased rapidly. However, the loss of natural cavities in the trees used as nests for these animals has greatly limited the recovery of their populations. A study in recent years recommended long-term conservation that combines environmental education in local schools, community involvement, and stricter penalties for hunters and the Lapa Roja habitat destroyers (Guittar et al 2008).

By Carolina Herrera, NRDC Wondering where that brightly colored songbird that visited your yard during the summer disappeared to when the temperature dropped? Many songbirds and other migratory birds spend the cooler months in Latin America’s tropical rainforests, so preserving their winter habitat is essential to their survival. That’s one reason why NRDC partnered with the group Osa Conservation to help Revive a Rainforest on Costa Rica’s Osa Peninsula, one of the most biodiverse places on Earth. With the support of our members we’ve been helping to restore 50 acres of degraded tropical rainforest by planting carefully selected native tree species. Six hundred and fifty species of birds make North America their home and breeding ground. While some of these birds are permanent residents many are migratory, with migration paths varying from short, medium to long. Approximately 350 species breed in the US and Canada and then winter all the way in Latin America and the Caribbean where they need to find sufficient food and safe nesting locations. The Yellow Warbler, Tennessee Warbler, and the Canada Warbler are just three of the many species that journey long distances during their seasonal migrations to Costa Rica’s Osa Peninsula.
Sea Turtles / 11.09.2012

One by one they go, leaving behind a trail of life in the sand. Seven weeks ago, after a journey spanning hundreds, perhaps thousands of kilometers, an adult olive ridley sea turtle (Lepidochelys olivacea) pushed through the foaming waves on Pejeperro beach in the Osa Peninsula, Costa Rica, to begin an ancient, unique and exquisite journey.

El siguiente es su relato de primera mano de su traslado a la Península de Osa. Hansel estado muy ocupado este verano, como la Tortuga Marina Programa de Voluntarios de 2012 está en marcha. Solicita hoy esta oportunidad para experimentar la maravillosa Península de Osa! [caption id="attachment_4049" align="alignleft" width="300" caption="Mamon Chino (Photo: Mario Melendez)"][/caption] El primer vistazo de Osa sucedió justo antes del atardecer en una tarde lluviosa de julio. A la orilla del camino, poco a poco se asomaba un mundo nuevo y mágico; una tierra que mezcla la selva con el mar. Rápidamente se llenaron mis pulmones con decenas de olores nuevos: el dulce aroma del Mamon Chino (Nephelium lappaceum), el suave olor de la Carambola (Averrhoa carambola), la hediondez del Nonis (Morinda citrifolia), el pudoroso Mimbro (Averrhoa bilimbí), la Guaba (Inga edulis), el cacao (Theobroma cacao), y otros mas. Ay, que lugar de ensueño pensé, y pronto olvide como había llegado hasta allí.

By Hansel Herrera Vargas Hansel Herrera Vargas, a Costa Rican biologist with a Bachelor's degree from Berry College, Georgia, USA, is Osa Conservation's new volunteer coordinator. The following is his first-hand account of his move to the Osa. Hansel  has been very busy this summer, as the 2012 Sea Turtle Volunteer Program is well under way. Apply today for this opportunity to experience the wonderful Osa Peninsula! [caption id="attachment_4049" align="alignleft" width="300" caption="Mamon Chino (Photo: Mario Melendez)"][/caption] I embarked on my first journey to the Osa Peninsula just before sunset on a rainy July afternoon. The road south brought glimpses of a magical landscape where the  jungle mixes with the sea. My lungs filled with dozens of new scents: the sweet smell of Mamon Chino (Nephelium lappaceum), the soft smell of Carambola (Averrhoa carambola), the stench of Nonis (Morinda citrifolia), the Mimbro fruit (Averrhoa bilimbí), guava (Inga edulis), cocoa (Theobroma cacao), and many others. The road to Puerto Jimenez brings one across many rivers and many histories. There are dozens of towns and cities dotting the road from Costa Rica's capital to the Osa, and the nine hour bus ride is filled with sightings of beautiful mountains and valleys, exotic birds, and ancient trees.
