Priorities for Future Research

Population and demographic rates are not well-known for this species. While this is a common species throughout its range, it is important to understand the demographic parameters for the species, as well as potential threats and limiting factors, to understand past and future changes in distribution and abundance. Extent of variation in vocal repertoire, particularly geographic variation, has not been studied. The physiological needs of the species (e.g., energy requirements, nutrition, metabolism, temperature regulation) are not known.
