Resources other than food, such as nest sites and roosting sites, can also result in limited opportunities for successful dispersal (Restrepo and Mandrag6n 1998). For instance, cooperative breeding is relatively uncommon among fruit specialists, perhaps because of the loose territorial system seen in many frugivores owing to the abundance and changing availability of fruit and the difficulty of defending it (Brown 1987). Cooperative breeding does occur in frugivores like hornbills (Witmer 1993), and toucan barbets (Restrepo and Mandrag6n 1998), which defend nesting and roosting cavities.
