group display in the socially monogamous northern double-collared sunbird (cinnyris reichenowi).	several sunbird species (nectariniidae) exhibit group display, but the function of this behaviour still remains unclear. we test two hypotheses (reproductive tactic and joint territory defence) to explain the function of this behaviour using data gathered on northern double-collared sunbirds (cinnyris reichenowi) from the cameroon mountains. sunbirds exhibited group display throughout the breeding cycle. groups of birds were mainly comprised of neighbouring pairs aggregated at territory boundari ...	2014	24345518
asymmetric competition for nectar between a large nectar thief and a small pollinator: an energetic point of view.	there are two alternative hypotheses related to body size and competition for restricted food sources. the first one supposes that larger animals are superior competitors because of their increased feeding abilities, whereas the second one assumes superiority of smaller animals because of their lower food requirements. we examined the relationship between two unrelated species of different size, drinking technique, energy requirements and roles in plant pollination system, to reveal the features ...	2017	28138819
