World Environment Day, 2nd Anniversary of the Luis Jorge Poveda Álvarez Arboretum and inauguration of the Centenary Forest. In early June, we had three important celebrations: World Environment Day, the 2nd anniversary of the Jorge Poveda Álvarez Arboretum and the inauguration of the Centenary Forest. World Environment Day was celebrated in early June, and had participation from diverse groups of people. We had students from various educational centers participate as well as people from organizations and businesses with various fields of focus, like mangroves in the case of Fundación Neotrópica, sea turtles in the case of LAST (Latin American...

Birds, Land Conservation and Forest Restoration / 05.12.2012

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.

[caption id="attachment_4712" align="alignleft" width="300"] RFA's and interns pose for a photo at our annual Sea Turtle festival this past September[/caption] November is the peak of the rainy season here in Osa, an ideal time for staying in, curling up with a good book and listening to the sheets of rain pelt the tin roof. Not so for the OC staff and our brave visitors and volunteers who have been working rain and shine to help us with various conservation projects! This month we're finishing up the Sea Turtle season and will be saying our goodbyes to our amazing Research Field Assistants that have made the program possible. Sai, Emily, Bre and Katie, we are incredibly grateful for your dedication and contribution this season. Thank you also to Katharine, Jamie and Alyssa, our field assistants who joined us for the first half of the season and all of our volunteers.

[caption id="attachment_4672" align="alignleft" width="493"] Photo by Manuel Sanchez Mendoza[/caption] If you've ever spent the night in the rainforest you know how deceptive sound can be. Unlike the intriguing daytime peeps, flaps, buzzes and calls that inspire one to explore deeper into holes, hollows, and underbrush, the haunting sounds that pierce the blackness of night cause the uninitiated like me to wholeheartedly question their disbelief of ghosts, goblins and spell-casting forest witches. Nighttime at Piro has a way of transforming torrential downpour into slowly approaching footsteps, guttural howler calls into sinister forest cries. Especially haunting is one sound that I really would have sworn was a ‘bruja’ laughing slowly and eerily into a wooden whistle repeatedly throughout the night.

By Katie Mascovich [caption id="attachment_4646" align="alignleft" width="300"] The green sea turtle's wounds are healing naturally[/caption] No two night patrols on the Osa are the same, but they usually have the same rhythm. Every now and then, however, something unexpected happens that makes the whole night worthwhile. On November 3, I had one of these experiences. But to fully understand it, I have to tell you about the patrol I had on October 21. That night I was patrolling Pejeperro Beach with Emily, another Research Field Assistant. It was one of those long nights where we knew we would not be back to the station and in our beds until dawn.
Science and Research / 26.10.2012

While the Osa Peninsula, rich with biodiversity and sheer beauty, is a wonderful place to kick back and relax, there are numerous opportunities for visitors to catch a glimpse of some of the world's most fascinating reptiles. Some of which, like the Terciopelo, can be especially hard (and dangerous) to spot. The Terciopelo is a beautiful dark grey, brown or olive green snake, with a dorsal pattern of triangular designs on both sides of its body, resembling a letter 'X' visible from above. It’s a large snake that can grow up to 250 cm (over eight feet!) in length, although the average adult is between 140 and 180 cm (4.6 to 5.9 ft) long. The females are much longer than the males. It principally eats small mammals and birds. The species is viviparous, which means that the embryos grow inside of the mother and are born fully formed. Furthermore, the snake is very fruitful; it can give birth to up to 90 offspring. This high fertility explains in part why the Terciopelo is one of the most abundant snakes in Costa Rica.

[caption id="attachment_4566" align="alignleft" width="300"] Mogos Islands mark the highest waters of Golfo Dulce.[/caption] By Brooke Bessesen While Jorge and I both loved working on the water, the results of our research brought the greatest rewards. Golfo Dulce is a true bio-gem—one of Costa Rica’s preeminent riches. Several hundred Green sea turtles, critically endangered Hawksbill sea turtles, Olive Ridley sea turtles and (reportedly) Pacific Leatherback sea turtles, rest, feed, mate and nest in the gulf. A rare xanthic colony of pelagic sea snakes resides around the inner basin. Both Northern and Southern Hemisphere Humpback whales enter the inlet to give birth and possibly provide sanctuary for young calves. Whale sharks aggregate in Golfo Dulce. Resident dolphins and other toothed cetaceans breed and raise offspring. Scalloped hammerhead sharks are born there and needlefish spawn. What a remarkably vibrant bionetwork!

Along with a few other ASCONA volunteers, Daniel, as he prefers to be called, is part of an extremely passionate group of activists protesting an American business-owner's proposal for a large marina development project on the Gulfo Dulce, a proposal met with considerable opposition among Osa residents and various conservationists on and around the peninsula.

By Brooke Bessesen [caption id="attachment_4304" align="alignleft" width="300"] The name "Brown pelican" belies the attractive hues of a mature bird.[/caption] I’m sure it comes as no surprise that during our 400+ hours of observation in Golfo Dulce, Jorge and I witnessed an astonishing array of marine life. Indeed, we were astounded by the intense biodiversity revealed to us during our research. In addition to the animals I’ve already blogged about in this series, many more are worth mentioning. Some were officially documented, others were not, but all helped define our emerging portrait of Golfo Dulce. Brown pelicans (Pelecanus occidentalis) are commonly seen in Golfo Dulce and we located a year-round communal roosting area along the banks of Piedras Blancas National Park in the upper half of Golfo Dulce. We saw many other marine birds, too, including Brown boobies, magnificent frigates, osprey, several species of gulls, terns, swallows, herons, ibis and dozens more wading and estuary birds.
Sea Turtles / 22.08.2012

By Jamie Cone [caption id="attachment_4122" align="alignleft" width="300" caption="Photo: Claudio Giovenzana"][/caption] An anticipatory rumble of thunder sounds far away, off shore. It has an almost calming sound as we make our way through the dark squishy forest path, the sky patterned with silhouettes of tree leaves. The jungle is alive with night sounds, from the echoing song of the nightjar to the almost space-invader beep of frogs on Las Rocas trail. A silky white two-toed sloth is spotted, high up in a tree, taking the night off. I envy its slow slumber for just a moment before I remember that this trail is taking me down to the beach, down to witness a spectacular and sacred event, one that only a few people in the world have the chance to be a part of. Tonight, I am walking a stretch of beach along which nesting mother sea turtles will, with great care and diligence, lay their precious eggs in the sand.
