Abstract : Field work at the Guama Ecological Research Area on the outskirts of Belem, Brazil, continued through 21 August 1969. The data consist of information on birds captured with mist nets in three tropical forest environments: high ground (terra firme) forest, igapo or permanent swamp forest, and riverine or varzea swamp forest which is flooded by tidally induced fluctuations of the river level. The following information was recorded: band number, weight and amount of subcutaneous fat, indications of reproduction such as brood patches or cloacal protuberances, detailed notes on molt if any, sex, age, presence or absence of Trombiculid mites, number of ticks if any, net number, shelf of net in which bird was captured, time, soft part colors if necessary for subsequent sexing and aging, degree of skull ossification and color of excrement if this might provide clues as to food habits. Generally a small blood sample was taken and a blood smear made. The smear was for later examination for haemaparasites. The blood sample was used for virus isolation and then tested for antibodies to eighteen different arboviruses by a haemaglutination-inhibition test, or tested for antibodies against one of three viruses including St. Louis Encephalitis by a neutralization test in tissue culture.
