Vastanavidae is an extinct family of birds related to parrots and passerine birds. They are known from fossils from Eocene sites in India, Europe, and North America. The vastanavids resemble parrots and the extinct parrot relative Quercypsitta in their morphology, including the partially zygodactyl foot, in which two toes could face opposite the other two.
