Super Hummingbirds
2016 · Film · documentary · 53 min
Hummingbirds are amazing creatures to behold. They are the tiniest of birds, yet possess natural born super powers that enable them to fly backwards, upside-down, and float in mid-air. Their wings beat faster than the eye can see and the speed at which they travel makes people wonder if it was indeed a hummingbird they actually saw. They also are only found in the Americas. These attributes have both intrigued scientists and made it challenging to study the species, but with the latest high-speed cameras and other technologies, Super Hummingbirds reveals new scientific breakthroughs about these magical birds.

“Humming birds have the highest metabolic rates of any invertebrates”
Im not sure if this is an accurate correlation, but i recall hearing;
The reason for mega flora and fauna (really large animals and plants) was due to a much higher % of oxygen in the atmosphere....
However, on the conspiracy spectrum, there was this russian kid who supposedly channeled living previously on mars who states that they had really really long life spans, but it is the fact that life on earth consumes much more oxygen, and it is oxygen that reduces overall life span - which is interesting when rated to vedic ancient books which talk of lives being ~900 years plus....
Only idiots downvote without comment...

So the documentary i linked to states that hummingbirds have developed a hemoglobin that absorbs oxygen at even 6% which is the same as 40,000 feet - as compared to 21% at sea level....
