White patches in the Painted Redstart (Myioborus pictus) are adaptations to flush prey during flush-pursue foraging which is characteristic for this species. Conspicuousness of white wing patches was measured in terms if time needed for a human observer to find a taxidermic model in a natural habitat. The time to find a model without patches do not confer higher conspicuousness to non-moving redstarts. The results are discussed in terms of predation risk from such visually orienting predators as hawks or or pygmy owls, and in comparison to other Myioborus species, all which do not posses the white wing patches.
