Abstract : The individual behavior of foraging bees was analysed at low-reward conditions within a collective context. This study compared bee-s foraging behavior under non-competitive individual and highly competitive collective conditions. A regular pattern in the visitation, non-visitation times and the frequency of foraging bouts was observed in bees that collected individually. In contrast, when bees foraged collectively, they demonstrated great variability in their behaviors. Some bees had regular visits to the feeder while others had only sporadic bouts. Individual foraging parameters related to the -persistency- at the feeder were well correlated with the prior foraging experience at this site. Results suggests that prior experience at a feeding place and efficiency as nectar carriers are positively correlated during collective foraging.
