Eli5 : why are bigger birds generally faster than smaller birds?

191 views

The way I think about it, smaller birds have less weight and less wind resistance. Shouldn’t that mean they would be faster?

Everyone talking power.

But it is more down to weight and gravity. A specific mass has a specific terminal velocity, and the heavier you are the higher that is.

Big birds also tend to glide. So they are faster just because they are heavier.

In a “flapping power contest” with no gliding, small birds are deffinitivly faster.
