ABSTRACT

Sixpairs of Volatina jacarina have been studied under captivity condition. Territorial defense was displayed by male as well as by female, through agonistic displays joined to characteristic vocalization. Several vocalizations have been identified and described. Courtship behaviour have also been observed. Male and female contributed both to the building of the nest, which is of the cup type, but the male alone was responsible for the chosen place. The average number of eggs by clutch was 2.3 (n = 2.8). Incubation have been depending on the sole female and the average incubation period was 10.6 days (n = 10). Both male and female fed the young with small arthropods and seeds. Nestlings remained in the nest for nine days (n = 9). A gular sac was present in the adults while they fed their young. Independence of the young was adquired in about one month. An internuptial plumage appeared during the non-reproductive period.
