More than ever it is important to build the capacity to make intelligent con- servation decisions to manage land in ways that are compatible with the needs of Osa’s flora and fauna, and to continue to under- stand exactly what species depend on the The elusive turquoise cotinga is one of four endangered Osa. Moreover, there is the need to build a bird species we are working to protect (see page 4). www.osaconservation.org Photo by Daniel Lebbin Page 2 FRIENDS OF THE OSA NEWSLETTER OSA BOTANY An orchid bee visits Martinella obovata flowers (photo by R.

Aguilar) The Osa is fortunate in having one of Costa Rica’s finest field botanists as a resident, Reinaldo Aguilar, who lives in Los Charcos de Osa (www.osaresearch.org). Reinaldo’s wife Cath- erine is known as an extremely talented botanical illustrator, and together they are making many new discoveries about the Los Charcos de Osa (www.osaresearch.org) importance of the Osa’s incredibly diverse flora. Reinaldo has joined forces with Scott Mori, a renowned botanist at the New York Botanical Garden, to document exhaustively what plants can be found in the Osa. With the support of Beneficia Foun- dation and private donors, Reinaldo is entering a new phase of plant collection and photographic documentation. He is col- lecting seeds of especially rare and interesting plants for propa- gation at the Osa Biodiversity Center and at Los Charcos. Friends of the Osa is interested in speaking with land owners who would like to have rare and important tree species for their own personal reforestation efforts. Right: Map of where specimens of endemic plants in the Osa have been registered. Most of the 1 km square cells have no collections registered, and in fact the heavily collected areas reflect where Reinaldo has lived and worked over the past decade. Our goal is to survey every cell in the grid. Page 3 FRIENDS OF THE OSA NEWSLETTER BIG PREDATOR UPDATE Aida Bustamante prepares a camera trap (photo by S. Menke) A puma pair caught on film! (Photo by Bustamante & Moreno) Jaguars are important keystone predators, and their presence in the corri- dor is promising news for conservation (Photo by A. Bustamante) Aida and Ricardo have found an astonishingly high density of ocelots in the area (Photo by Bustamante & Moreno) It’s well known that Costa Rica’s national parks are virtually all too small to adequately support animals such as jaguars and harpy eagles that require extensive areas. Friends of the Osa researcher Aida Bustamante, working with Ricardo Moreno, has been using an ambitious camera trapping grid in the area between Matapalo and Corcovado. They have shown how extremely important this private land is to the cats of the Osa. They have recorded at least 4 jaguars, 19 puma, and 18 ocelots, along with margay and jaguarundi, in the corridor. We would like to thank all of the landowners who have assisted in allowing placement of camera traps on their properties. Any landowners who would like to engage in a camera trapping survey and are willing to purchase and install cameras on their property are invited to contact us for details on how to collaborate. Aida and Ricardo’s cam- era traps record not just the presence of cats, but also other wildlife, and we are pleased to report that populations of Collared peccaries are smaller in size and travel in smaller groups than peccary, large game birds, and other wildlife that have been their white-lipped cousins. They are important prey for large cats. (Photo by Bustamante & Moreno) heavily hunted in the past appear to be recovering. FRIENDS OF THE OSA NEWSLETTER Page 4 M ATE CHOICE BY TUNGARA FROGS Our lab is interested in understanding the sensory neurobiology of animal communi- cation. Currently, our research is focused on examining the neural bases of elaborate male traits in the túngara frog (Physalaemus pustulosus) among other projects. My own research is focused towards understanding the neuro-endocrine mechanisms that influence female mate choice decisions in the túngara frogs. I study the effect of steroid hormones such as estradiol in influencing neural pathways that may influence female auditory responses towards conspecific calls.

These include the Man- grove Hummingbird, Yellow-billed Cotinga, Turquoise Cotinga, and Black-cheeked Ant-Tanager. Recently, Dr. Daniel Lebbin visited the Bosque del Río Tigre Lodge (www.osaadventures.com). There, he introduced lodge owners and naturalists, Elizabeth Jones and Abraham Gallo, to basic bird monitoring techniques. These included marking and mapping trails, territory mapping, and data entry according to eBird protocols. They conducted pre- liminary surveys at several sites across the Gulfo Dulce and Osa Peninsula, recording valuable data for all four species. Ongoing work will continue to assess the populations and distributions of these birds, and identify further conserva- tion actions. More information about the spectacular birds The black-cheeked ant-tanager is one of four endangered species endemic of the Osa Peninsula and their conservation will be posted to the region (photo by Daniel Lebbin) soon at the Friends of the Osa website. FOO WELCOMES NEW DIRECTOR Friends of the Osa has a new director based in our Puerto Jimenez office. Gerardo Solorzano is a well known Costa Rican conserva- tionist who has worked in other areas such as Guanacaste. He can be frequently found in the field, as well as in San Jose. Gerardo is fluently bilingual and is experienced at working with different groups of stakeholders and communities. We expect he will build strong relationships with local communities and residents of the Osa. Gerardo welcomes input from people interested in conserva- tion on the Osa, and you can contact him at our Puerto Jimenez office: Tel +506 735-5754, [email protected] FRIENDS OF THE OSA NEWSLETTER Page 5 S EA TURTLE NESTING SEASON DRAWS TO CLOSE This year our sea turtle pro- gram, led by Program Man- ager Gioconda Retana, was housed in the beach “house” of FOO board member Bill Abraham (former residence of Osa conservation pioneer, Manuel Alonso). This tem- porary base allowed us to have a presence on the beach every day and every night of the turtle nesting season. As a result, we be- Local school children learn more about the importance One of our sea turtle volunteers releases a baby turtle lieve the poaching rate from of conserving Osa’s sea turtles from the hatchery Matapalo to Rio Piro has been reduced to almost zero for this year’s nesting season. However, coati (pizote) pre- dation of eggs has been very high, and we are considering whether we need to actively manage their predation levels by relocating most eggs to our new turtle hatchery.
