Lists of birds by population

From Wikipedia, the free encyclopedia
Jump to: navigation, search

This is a collection of lists of bird species by global population, divided by orders. 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.

These lists are incomprehensive, as not all birds have had their numbers estimated. The Spectacled Flowerpecker was only discovered in 2010, and has yet to be given a scientific name, added to the 73 new bird species described from 2000 – 2009.[1][2][3] Global population estimates for many of these at this time would be absurd. Again, all numbers are estimates, 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] These lists 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 these lists are meant to convey.

Estimation is accepted practice amongst demographers, and the data included here should be considered no less scientific than that found in anthropological articles like List of countries by population. The 2010 United States census participation rate was 74%;[10] populations in Somalia are ascertained using satellite imagery;[11] the human denizens of Bhutan, according to the national government, number 708 265, while the CIA World Factbook has given figures as high as 2,327,849.[12][13] All populations, be they human or bird, are estimates.
