“…Thus far this group is represented by only two species, the noctilionid bat Noctilio labialis, studied in Panam'a (Anderson and Wimsatt, 1963), and the phyllostomid bat Glossophaga soricina, studied in Matto Grosso, Brazil (Hamlet, 1935). However, the latter is doubtfully placed in this category since the pattern was deduced from only a few specimens taken at one time of the year, and in Mexico (Cockrum, 1955) and Colombia (Tamsitt and Valdivieso, 1964), G. soricina apparently has no restricted breeding season. In the second group are those species which have no well-defined sexual season and breed throughout the year.…”

ABSTRACT:Reproductive activity of males of the tropical frugivorous bat, Artibeus lituratus, was investigated in west central Colombia for a 17-month period during 1961-1963. The climate of the area varied little throughout the study period, and climatic conditions did not influence reproductive activity in males. Data based on presence of sperm, length and tubule diameter of the testis and diameter of the epididymis indicate that males are capable of reproductive activity at any time of the year, and the reproductive pattern is acyclic without suggestions of seasonal variations.

“…Copulation apparently is initiated in flight. Counts of embryos per female (n = 45) of L. b. borealis average 3.2 (Cockrum, 1955;Jennings, 1958;Layne, 1958), but the number of young born per litter ranges from one to five (Hamilton and Stalling, 1972;Mumford, 1973), with an average of 2.3 (Birney and Rising, 1968;Constantine, 1966;Jones et al, 1967;McClure, 1942). Mumford (1973) suggested that most young are born in mid-June in Indiana.…”
