The family Todidae is endemic to the Greater Antilles. Hispaniola is the only island that hosts multiple tody species: the Broad-billed Tody and Narrow-billed Tody. Ornithologists know almost nothing about these two species. We aim to study behavioral interactions between the species, and to investigate whether they are hybridizing. We are also interested in the possibility that tody geographic distributions and interbreeding might be influenced by climate change.
