Calls were recorded from captive females of Tamias sibiricus that were in estrus. Calls were short, sharp broadband "chips" given in series. There were three types of calls, a frequency modulated call, a simple constant-frequency call, and a two-note constant-frequency call. From behavioral contexts, it appeared that the frequency modulated call, given at fast-repetition rate, was an advertising call, and all three, given at slow rates, were courtship calls used during close interaction with the male.
