Research on hybridization has focused mostly on plumage, particularly in taxa like the bearded manakins Manacus spp. that differ from each other mainly for the colour of the collar and of the underparts. By using high-speed videography and slow-motion analysis, we found that hybrids perform courtship displays that are intermediate between the two parent species. In particular, the colour and the choreography show different degrees of similarity with either parent species, suggesting that courtship behaviour is involved in speciation processes in this avian taxon.
