We would like to announce a 10 day field intensive focused on cetacean behavioral ecology in Puerto Rico. Join our research team studying Humpback Whales *(Megaptera novaeangliae)* Wintering off Puerto Rico. This field intensive training program is well suited for students (undergraduate and graduate) of all skill levels interested in cetacean behavioral ecology, and conservation. The field intensive culminates in a certificate acknowledging training including: research experience in data collection and recording, photographic techniques under a variety of conditions, photo identification of individual humpbacks and dolphins, theodolite tracking and computer interface, passive acoustic sampling, scanning for marine mammals from a land based field station, estimating group size, distinguishing between calf, juveniles and adults, assessing environmental factors including sea state, permit requirements for marine mammal research involving endangered species, and overview of ecology on this island bordered by the Caribbean Sea and the Atlantic Ocean. The price is $1500.00 per student and includes travel between field stations, training program in scientific methods, scientific supervision, room and board at the project base station, reference materials related to the project, including field methods, and a certificate of completion. Fees do not include travel to and from the base station in Puerto Rico and compulsory insurance. 100% of fees support this research project and associated lectures. To apply for this field intensive, send a request for an application and information packet to mithriel.mackay@gmail.com. The application packet includes a description of the project, dates for each field intensive 10 day session, the base station where students will sleep during this field intensive, and an application check list. Space is limited to 2 interns for each 10 day field intensive. Sessions begin January 2011 and continue through the end of March 2011. -- Mithriel M.
