Mr. Clarke et al., GROUP TAKEOVER BY A NATAL MALE HOWLING MONKEY (ALOUATTA-PALLIATA) ANDASSOCIATED DISAPPEARANCE AND INJURIES OF IMMATURES, Primates, 35(4), 1994, pp. 435-442
As part of a long-term study on howling monkey behavior and social dyn
amics, a known natal male was observed taking over his group from his
putative sire. Due to the accidental death of one of the adult males,
this natal male had matured in a one-male group and had never observed
juvenile male emigration nor adult male immigration and associated be
haviors. Nevertheless, the behaviors associated with the takeover were
indistinguishable from those of an immigrant male including disappear
ance of immatures, one of whom was found with extensive injuries. Whil
e it cannot be said that the natal male inherited these behaviors from
his presumed father, it can be said that he exhibited species-typical
behaviors associated with male takeover in the absence of observation
al learning.
