Abstract : Thirteen field trips in 5 locations have been made for animal collection and broad ecological surveys. Over 10,000 birds, bats, other mammals, and reptiles or amphibia have been captured in these studies, of which 4,000 sera have been collected and more than 2,000 animals skinned. Bled birds have been branded. Identification has resulted in adding 12 new species of birds with new knowledge on their distribution, status and breeding seasons. Identification of other groups including bats and amphibia is proceeding more slowly due to the general lack of knowledge of these groups in that country. Feeding habits will be studied from analysis of stomach contents and ectoparasites collected when possible. Preliminary results of serologic studies (1350 sera) show few regional differences and low prevalence of antibody to group B arbovirus antigens in birds, bats or rodents, but high prevalence in monkeys (43/43 tested) from one region. When birds are separated by species a high figure is obtained for one of them--the African Thrush (Turdus pilios). The results of intensive field work in the project's first year indicate that it may take longer than originally planned to obtain adequate samples of the more abundant species in each area, but emphasis will be placed on those of greatest epidemiological importance.
