Environmental Education, Miscellaneous / 23.09.2010

This August 16-19, La Leona Lodge organized a workshop about frugivorous (that means fruit-eating) butterflies with entomologist and curator of Lepidoptera, José Montero of INBio (National Biodiversity Institute of Costa Rica). This workshop was attended by several people in the area, including naturalist guides and employees of La Leona Lodge. José taught us about the methodology that he has been using in different parts of the country with great success for several years and now La Leona Lodge has begun to use, in order to generate information about butterflies of...

In 2008, in order to determine the distribution and abundance of leaf litter amphibian species, I began a monitoring program around the Piro Research Center along with Federico Bolaños and Gerardo Chaves, herpetologists from the University of Costa Rica. In 2010, with the support of the Mohamed bin Zayed Species Conservation Fund (MBZ), I expanded this project to Los Charcos and Petosa, a private property owned by Bert Kerstetter, an important supporter of Friends of the Osa. The information generated by this project was included in the latest update workshop...

[caption id="attachment_1416" align="alignleft" width="300" caption="Chestnut-backed Antbird. 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.

[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...

[caption id="attachment_1189" align="alignleft" width="300" caption="Common Pauraque by Karen Leavelle"][/caption] Have you ever been out at night driving along a country road and been startled by red ember eyes darting across the hood of the car, and then to have it happen every few hundred meters or so?  If you are driving anywhere on roads, especially dirt roads, from South Texas on down to Argentina you are bound to see the Common Pauraque (Nyctidromus albicollis). Here on the Osa Peninsula on the road to the Osa Biodiversity Center it is...

[caption id="attachment_1122" align="alignleft" width="254" caption="Blue-crowned Motmot by Alan Dahl"][/caption] The Blue-crowned Motmots (Momotus momota) have been spending a lot of time around a Nance tree (Byrsonima crassifolia), a prolific fruit producing tree in the garden here at Friends of the Osa’s Osa Biodiversity Center.  Lately there have been quite a few hanging around giving their distinctive soft low pitch “moot moot” call at dawn which has sounded like a large choral group, each bird with its own perfectly timed solo, and the group never missing a beat.  With...
