Nature: According to a study, the Earth has about 50 BILLION birds, or six for every human on the planet.
There are roughly 50 billion birds alive on the Earth today, a big data study has found — the equivalent of around six for every individual human on the planet. Pictured: the house sparrow, which — despite being endangered in the UK — appears to have the largest global bird population at 1.6 billion individuals
Researchers from Australia's University of New South Wales (UNSW) estimated how many birds there are across 9,700 species, all the way from pigeons (left) to penguins (right)
'BILLION CLUB' BIRDS The researchers found that only four bird species belong to what they have dubbed 'the billion club'.These are those whom the algorithm has estimated as having a global population of more than one billion.The 'billion club' includes:the h ouse sparrow (1.6 billion)the European starling (1.3 billion)the ring-billed gull (1.2 billion)and the barn swallow (1.1 billion)Advertisement
