Three zebra finches were trained with operant techniques to respond to pure tones. Absolute thresholds were obtained for nine durations of a 3‐kHz tone and five durations of a 1‐kHz tone. The temporal integration functions finches were described using the negative exponential function proposed by Plomp and Bouman [J. Acoust. Soc. Am.31, 749–758 (1959)]. The time constants obtained for zebra finches are about 250 ms, which are similar to those reported for a number of species, including humans and other bird species.
