摘要:
AbstractVocal behavior of four pairs of adult Sichuan golden monkeys was studied at the San Diego, Seattle, Los Angeles, and San Francisco zoos between November 1984 and October 1986. Four call types made up 86% (1,357/ 1,578) of vocalizations that occurred during 45 h of tape‐recording. All four major vocalization types were made by both sexes. There was, however, significant sexual asymmetry in their production: 82% to 99% of each type was produced by one sex or the other. Frequently, duets developed when an individual male or female responded to the vocalizations of its cagemate. Males vocalized more than did females in each of the four pairs, and males responded vocally to female calls more than twice as frequentl
