Thicket tinamou, Crypturellus cinnamomeus LC.

Highland tinamou, Nothocercus bonapartei LC.

They are related to the ratites (order Struthioniformes), which includes the rheas, emus, and kiwis. Although they look similar to other ground-dwelling birds like quail and grouse, they have no close relatives and are classified as a single family, Tinamidae, within their own order, the Tinamiformes. The tinamous are one of the most ancient groups of bird. 2019, the data is current as of July 25, 2019Д® - endangered, T - threatened XN, XE - experimental non essential or essential population E(S/A), T(S/A) - endangered or threatened due to similarity of appearance (including taxa not necessarily found in the USA, the data is current as of March 28, 2014

The following codes are used to denote certain categories of species: Unless otherwise noted, all species listed below are considered to occur regularly in North America as permanent residents, summer or winter residents or visitors, or migrants. The Sibley-Ahlquist taxonomy is an alternative phylogenetic arrangement based on DNA-DNA hybridization. The AOS's Committee on Classification and Nomenclature, the body responsible for maintaining and updating the Check-list, 'strongly and unanimously continues to endorse the biological species concept (BSC), in which species are considered to be genetically cohesive groups of populations that are reproductively isolated from other such groups' (AOS 2019). The taxonomic treatment (designation and sequence of orders, families and species) and nomenclature (common and scientific names) used in the accompanying bird lists adheres to the conventions of the AOS's (2019) Check-list of North American Birds, the recognized scientific authority on the taxonomy and nomenclature of North America birds.
