The Alston’s singing mouse is know for its high-pitched songs, vocalizations that they use to attract mates and keep rivals away. New research from the University of Texas has shown that their songs are also used to set boundaries. Both the Alston’s singing mouse (Scotinomys teguina) and their larger cousin the Chiriqui singing mouse (S. xerampelinus) live in the cloud forests of Panama and Costa Rica.
These two singing mice have separate territories, the boundaries of which they mark with a song. When the Alston males hear the song of their larger cousin, the Chiriqui mouse, they will stop singing and flee to avoid any trouble. Check out the video below to hear the Alston’s mouse high-pitched song.
