摘要

It has been suggested that the cohesion of mixed species flocks relies heavily on conspicuous species that act as an attractive nucleus for other birds. I evaluated the role of the White-flanked Antwren as a nuclear species in mixed-species flocks of gallery forests of eastern Colombia, and tested experimentally the hy- pothesis that the conspicuous wing-flashes of males contribute to interspecific cohesion. Although most of the species present in my study site showed a high propensity to flock heteroespecifically, interspecific associations of the White-flanked Antwren trended to be short.
