Telluraves would be the fifth grouping of Neoaves, after the previous four sections. This page focuses on two of the orders that have traditionally been known as birds of prey. Falconiformes is also an order of birds of prey but that order is more closely-related to the birds in section 37-XI than to the birds on this page.
- Telluraves
