The cotingas are a large family of suboscine passerine birds found in Central America and tropical South America.



Two subspecies of the White-tipped Plantcutter (Phytotoma rutila) might be in the early stages of ecological speciation. Genetic analyses uncovered gene flow from the highland (angustirostris) into the lowland (rutila) subspecies (Rodríguez-Cajarville et al., 2019).
