[The discrimination by the long-tailed Arctic suslik Citellus parryi of short frequency-modulated sounds].
Using conditioned reflex technique, ground squirrels have been examined for their ability to discriminate between species specific FM-shaped signals and synthetic sounds. The animals reliably distinguish a complex FM-signal from gradually sweeping downwards sounds only when they differed either in their duration or in steepness of FM sweep.
