Photo by Alan Dahl "][/caption] Chestnut-backed Antbirds (Myrmeciza exsul) are common residents of the Osa Peninsula and one of the most abundant species found here.  It is difficult to walk outside here at Friends of the Osa's Osa Biodiversity Center and not hear two or three individuals counter-singing.  Often times when the rest of the forest has become fairly quiet you can always count on a Chestnut-backed Antbird to let you know that all is as it should be. The signature look of three...

Community Outreach, Sea Turtles / 17.09.2010

On Sunday September 12 we celebrated the Second Annual Osa Peninsula Sea Turtle Festival on Carate Beach. The objectives of this annual event are to raise community awareness about the importance of joint actions in the conservation of the sea turtle species that frequent the beaches of the Osa Peninsula in the months of nesting, and to share the objectives and results of Friends of the Osa’s Sea Turtle Conservation Program with the community.

Community Outreach, Science and Research, Sea Turtles / 15.09.2010

By Phoebe Edge, Research Field Assistant of the Sea Turtle Conservation Program We are officially half way through this year´s turtle season and it has been a very busy 3 months indeed! Within this time, we have been continuously patrolling our beaches morning and night to help our favorite reptiles. There seems to never be a dull moment, even the walks to the beach prove exciting! Already, we´ve been fortunate enough to have encountered jaguarundi, coati, caiman, anteaters, armadillos, as well as a variety of beautiful and rare frogs...

[caption id="attachment_1341" align="alignleft" width="300" caption="Riverside Wren nest by Cheryl Chip & Jim Tamarack"][/caption] For those of you who may remember, I posted a feature on the Riverside Wren (Thryothorus semibadius) back in April.  It was one of my first postings for the then new Friends of the Osa's blog The Osa Chronicles and a few of you commented on both the nature history and photography by Gianfranco Gomez. One of the species ecological behaviors I wrote about was of reproduction and nesting.  When I spoke about the nest of...

Science and Research, Sea Turtles / 07.09.2010

Last month I shared with you the total data for in situ nests, nest predation and false crawls for the month of July, and mentioned that these data were not adjusted for sampling effort. By sampling effort, I mean the amount of time and / or distance that was invested on each beach to get the data. For example, we monitor 2 km of Piro beach and 4.5 km of Pejeperro beach.  So, it isn’t the same to walk Piro beach and find two turtles as it is to walk...

[caption id="attachment_1239" align="alignleft" width="240"] White-whiskered Puffbird by Gianfranco Gomez[/caption] Not only does the White-whiskered Puffbird (Malacoptila panamensis) rank pretty high on the cuteness scale, it is also an interesting species from an ecological perspective.  Puffbirds are most closely related to jacamars, toucans and woodpeckers.  They are primarily insect and arthropod eaters and are considered to be flycatching birds along with tyrant flycatchers, and nunbirds.  Even though they eat spiders, frogs and lizards taken from the ground they are known for sitting perfectly still in the forest understory until a...

El mes pasado compartí con ustedes los datos totales para nidos in situ, nidos depredados  y salidas falsas para el mes de Julio, y mencioné que estos datos eran sin ajustar por el esfuerzo de muestreo. Por esfuerzo de muestreo me refiero a la cantidad de tiempo y/o distancia que se ha invertido en cada playa para obtener los datos.  Por ejemplo, en Piro nosotros monitoreamos 2 km de playa y en Pejeperro, monitoreamos 4.5 km. No es lo mismo recorrer Piro una vez y encontrar 2 tortugas,...

Environmental Education, Marine Conservation, Sea Turtles / 21.08.2010

Friends of the Osa’s Environmental Education program is carrying out educational activities on the conservation of sea turtles and marine ecosystems in the schools of the Osa Peninsula. The objectives are for students to learn the importance of sea turtle conservation, why Golfo Dulce is a tropical fjord, and the ecological and scientific implications of this designation. Students learn about the four sea turtle species that nest every year on the beaches of the Osa Peninsula: Olive Ridley (Lepidochelys olivacea), East Pacific Green or black turtle (Chelonia mydas agassizii), Hawksbill...
