Answer 1

$\huge\mathtt\blue{タղՖWモℜ}$

About 10 years ago, two scientists decided to estimate the total number of birds on the planet. The number they came up with was 200 to 400 billion individual birds. Compared to 5 billion people, this amounts to about 40 to 60 birds per person. Your second question, unfortunately, is much easier to answer.

Answer 2

Answer:

10,000 to 13,000 bird species and 200 to 400 billion individual birds are the rough estimates to the question of how many birds in the world.
