SCAVENGING FRUGIVORE GUILD

 Though only two female Centurio were captured, one female preg-
 nant in February and another lactating in November indicate that the
 wrinkle-faced bat is probably seasonally polyestrous like other fruit
 bats.

 NECTAR-POLLEN-FRUIT-INSECT OMNIVORE GUILD

 The only reproductive data available for this guild is for
Phyllostomus discolor, which appears to follow the pattern of seasonal
polyestry explained for frugivorous guilds (Table 17).

SANGUIVORE GUILD

 Wimsatt and Trapido (1952) suggested that Desmodus rotundus
females are seasonally polyestrous or polyestrous year round. Turner
(1975) demonstrated that D. rotundus in cattle-raising areas of Dry
Tropical Forest in Costa Rica are pregnant or lactating in all months of
the year, but most pregnancies occur in the wet season. Although only
six female vampires were captured in my study, the appearance of

females captured. Data for species in the accompanying figures are not duplicated here. Data are from this study
and from bats captured in Panama by Fleming et al 1972.
