This is a list of bird species by global population, divided by

IUCN, BirdLife International, and Partners in Flight
.

The average global population of all mature birds is estimated to be somewhat less than 90 billion (actually, somewhere between 40 and 130 billion; this too is a rough estimate). The total population including younglings is somewhat higher during the breeding season of each species.[1]

This list is incomplete, because experts have not estimated all bird numbers. For example, the

ornithologists from 2000 – 2009.[3][4][5]
Global population estimates for many of these at this time would lack accuracy.

All numbers are estimates, because they are taken by

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.[8][9] 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).[10][11]
It is these large differences between species that this list tries to convey.
