Species accumulation curves for 1000-capture undergrowth mist-netting samples from terra firme forest of five Neotropical lowland areas. Enhanced from Karr et al. (1990). neus were missing only in Central Amazonia. Pipra mentalis belonged in the top 10 species only at the two Central American sites as well as at Playa de Oro. Even at the level of foraging guilds, similarities be- tween geographic regions were rather scarce. How- ever, some interesting patterns appeared. Apart from the previously mentioned bark-climbing insectivores, frugivores were the only other guild represented by at least one top 10 species at all sites. Three other guilds contained at least one species among the 10 commonest ones at five of the six localities: arboreal gleaning insectivores, nectarivores, and omnivores. The Rio Nambi sample was very distinctive in com- parison with the lowland sites. Three insectivorous guilds (terrestrial gleaning, ant-following, and ar- boreal sallying) were represented there neither by any TABLE 40.
