VOLUNTEER FIELD ASSISTANTS (2) needed for study of White-ruffed Manakins on the Atlantic Slope of Costa Rica. This study will examine the carry-over effects of altitudinal migration using physiological techniques, stable isotopes, and behavioral observations. Conditions are always wet, trails are very muddy, bugs can be bad, the day starts early, and accommodations are rustic. However, the biodiversity is fabulous, you will swim in the best waterfall ever, the food is good, and on days off, you can travel to other places in the country. Work will begin late Feb 2008 and continue until the end of Apr 2008 or early May. Assistants must be willing to commit to the full field season.

Applicants should have excellent personal and physical skills and mist-netting/banding experience. Prior experience bleeding birds, resighting small color-banded birds, working in the tropics, Spanish, and out-doors-(wo)man-ship all are pluses. I will cover all in-country expenses (travel, food, and accommodation). Please send a letter stating why you are interested in this position, a current CV, and the names, emails and phone numbers of three references to ALICE BOYLE via email

(EM: aboyle7@... ).
