Abstract
Presentamos el primer registro en territorio colombiano de Heterocercus aurantiivertex (Passeriformes: Pipridae) a partir de fotografías. Esta especie está presente en los bosques de várzea amazónicos del bajo Putumayo, en el Parque Nacional Natural La Paya. Nuestro registro es el primero de la especie al norte del río Putumayo (Iça), lo cual no resulta del todo sorprendente dadas las condiciones de continuidad de hábitat desde los bosques de Ecuador y Perú, hacia los bosques del departamento de Putumayo en Colombia, pero plantea un desafío en evaluar el río Putumayo como una barrera biogeográfica.
