INTRODUCTION Zuckerman (1953) presented detailed information on the season of births of mammals in captivity and attempted to compare these patterns with those of wild mammals. He concluded (p. 933) that « unfortunately there is little reliable information in scientific journals about the breeding habits of wild mammals, and it is usually difficult to evaluate the observations on this subject that appear in the naturalistic literature ». The reason for this is obvious : while the relative frequency of births by season can readily be observed for animals in captivity, direct observations of this kind are almost impossible to make on wild populations. Seasons of birth for wild mammals are usually expressed in hazy terms giving the months over which births or pregnancies have been known to occur and a guess at the « peak period » or « average date ».
