The average global population of all mature birds is estimated to be on the order of 100 billion individuals. [1] [2] [3] The total population including younglings is somewhat higher during the breeding season of each species. [3] This list is incomplete, because experts have not estimated all bird numbers.

In 2011 a study published in PLoS Biology estimated there to be 8.7 million ± 1.3 million eukaryotic species on Earth. [11] By 2017, most estimates projected there to be around 11 million species or fewer on Earth. [4] A 2017 study estimated there are around at least 1 to 6 billion species, 70-90% of which are bacteria. [4]
