Population Spatial Metrics

The “usual” size of nesting colonies is not entirely clear, though the fact that they tend to nest in smaller groups than other species is often stated (34, 3). This is perhaps a result of historical reports of smaller colonies (123, 196), but these may represent observations of only one nest cluster within a larger colony. Indeed, most reports suggest that colonies tend to encompass 10+ nests, but that the colony is often divided into several smaller clusters of nest that range from 2-6 nests each (192). Reports of larger colonies include: 2 colonies of 30+ nests (neivae; 178), colonies of 14 and 17 nests in Venezuela (yuracares; 192), and a tree containing over 60 nests in Bolivia (yuracares; 5).
