Abstract:
We conducted a brief radiotelemetry study of Scotinomys teguina (Alston’s singing mice) in Costa Rica to better understand their natural history and spatial ecology. We radio-collared five mice, one of which was quickly eaten by a pitviper. The home ranges of the remaining mice were in moist habitats and ranged from 255 to 1620 m², with extensive overlap between adjacent individuals. Singing mice, being small, diurnal, uniformly dark-colored insectivores foraging in dense forest floor habitats, have an adaptive syndrome similar to soricids, which may be due to the low diversity of shrews through Central America.
