Priorities for Future Research


Yellow-green Tyrannulet is very poorly known, and, as a small-bodied bird of the canopy of tall forest, it will be a difficult study subject. The known distribution is very small, although seemingly suitable habitat extends both to the north and to the south; perhaps this species has much narrower habitat requirements than currently is recognized. The nest has not been found at all, and there are no quantitative data on population density or population trends. The diet is not described in any detail. There also is no information for Yellow-green Tyrannulet on such topics as age at first breeding, life span and survivorship, dispersal, population regulation, molts, territoriality, and sexual behavior.
