This is a list of Tinamiformes species by global population. While numbers are estimates, they have been made by the experts in their fields. For more information on how these estimates were ascertained, see Wikipedia's articles on population biology and population ecology.
This list is not comprehensive, as not all Tinamiformes have had their numbers quantified.

The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is an inventory of the global conservation status and extinction risk of biological species. A series of Regional Red Lists, which assess the risk of extinction to species within a political management unit, are also produced by countries and organizations.
Tinamous are members of the order Tinamiformes, and family Tinamidae, divided into two distinct subfamilies, containing 46 species found in Mexico, Central America, and South America. The word "tinamou" comes from the Galibi term for these birds, tinamu. Tinamous are the only living group of palaeognaths able to fly, and were traditionally regarded as the sister group of the flightless ratites, but recent work places them well within the ratite radiation as most closely related to the extinct moa of New Zealand, implying flightlessness emerged among ratites multiple times. Tinamous first appear in the fossil record in the Miocene epoch. They are generally sedentary, ground-dwelling and, though not flightless, when possible avoid flight in favour of hiding or running away from danger. They are found in a variety of habitats, ranging from semi-arid alpine grasslands to tropical rainforests. The two subfamilies are broadly divided by habitat, with the Nothurinae referred to as steppe or open country tinamous, and the Tinaminae known as forest tinamous.
The Magdalena tinamou, Crypturellus erythropus saltuarius, is a member of one of the most ancient bird families, the tinamous. It is endemic to the Magdalena River Valley in Colombia, and had been considered possibly extinct, because of an absence of confirmed records since the type specimen was collected in 1943. The most recent review consider it likely that it is extant, as locals have reported sightings in the 1970s and 1980s, an individual was apparently held in captivity until the early 1990s, and a few patches of forest remain in its presumed range. Additionally, a record was made in late 2008. It was rediscovered in 2023.
The great tinamou is a species of tinamou ground bird native to Central and South America. There are several subspecies, mostly differentiated by their coloration.
Crypturellus is a genus of tinamous containing mostly forest species. However, there are the odd few that are grassland or steppe tinamous. The genus contains 21 species.
Berlepsch's tinamou is a type of ground bird found in moist forest in northwestern Colombia and northwestern Ecuador.
The slaty-breasted tinamou or Boucard's tinamou is a type of tinamou commonly found in lowland moist forests of Mexico and Central America.
The Choco tinamou or Chocó tinamou is a type of tinamou found in lowland forest and montane forest in subtropical and tropical regions of Colombia and Panama.
Tinaminae, the forest tinamous, is one of two subfamilies of the family Tinamidae, the other being Nothurinae.
