Diurnal bird visiting of Caryocar brasiliense Camb. in Central Brazil

Nectar of nocturnal flowers may be used by diurnal species that occasionally accomplish secondary pollination. Thirteen bird species visited Caryocar brasiliense flowers in central Brazil. There is a temporal separation between nectarivores and non-nectarivores species. Nectarivores birds visited flowers late in the morning, while other species appear earlier. C. brasiliense nectar may be an alternative resource to birds visitors during the dry season.
