List of birds by population

This is a list of bird species by global population, divided by bird classification. 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. Contributing organizations include the IUCN, BirdLife International, and Partners in Flight.

This list is incomplete, because experts have not estimated all bird numbers. For example, the spectacled flowerpecker was only discovered in 2010, and has yet to be classified with a Linnean name, but would add to the other 73 new bird species described by ornithologists from 2000 – 2009.[1][2][3] Global population estimates for many of these at this time would lack accuracy.

All numbers are estimates, because they are taken by observation, and a given number of 50 slender-billed curlews does not necessarily mean there are 10 more of this species than the black stilt, which has been estimated at 40: there is a possibility that the latter species has a larger population than the former.[4][5] This list should not be taken that literally. An estimate of 250 shore dotterels compared with 4,500 – 5,000 wrybills, on the other hand, means that the latter has well over one order of magnitude more individuals than the former.[6][7] The wrybill only has approximately one tenth the population of great skuas (48,000), which are outnumbered ~10:1 by the pigeon guillemot (470,000).[8][9] It is these large differences between species that this list tries to convey.

List of bats by population

This is a list of bat 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 bats have had their numbers quantified.

List of carnivorans by population

This is a list of estimated global populations of Carnivora species. This list is not comprehensive, as not all carnivorans have had their numbers quantified.

List of even-toed ungulates by population

This is a list of even-toed ungulate species by estimated global population. This list is not comprehensive, as not all ungulates have had their numbers quantified.

List of odd-toed ungulates by population

This is a list of odd-toed ungulate species by estimated global population. This list is not comprehensive, as not all ungulates have had their numbers quantified.

List of primates by population

This is a list of primate species by estimated global population. This list is not comprehensive, as not all primates have had their numbers quantified.

Lists of mammals by population

This is a collection of lists of mammal species by the estimated global population, divided by orders. (Lists only exist for some orders; e.g. the most diverse order - rodents - is missing.) Much of the data in these lists were created by the IUCN's Global Mammal Assessment Team, which consists of 1700 mammalogists from over 130 countries. They recognize 5488 species in the class.These lists are not comprehensive, as not all mammals have had their numbers estimated. For example, a live specimen of the spade-toothed whale was first observed in December 2010, and the event only recognized as such in November 2012; no estimate yet exists for the global population. The accuracy of the quote numbers may only be an order of magnitude.

It is estimated that the total number of wild mammals in the world is about 130 billion.
