The high metabolic price of staying in the air
In short: Flight is a biological masterpiece, but it comes with a steep energy bill. This video explores why various bird species have independently traded the ability to fly for other evolutionary advantages.
While the common ancestor of all modern birds possessed the ability to fly, many species have since lost this trait. Evolution often favors efficiency; while flight offers benefits like predator evasion and long-distance travel, it requires massive amounts of energy and imposes strict limitations on body size and weight.
By abandoning flight, certain birds can bypass these high metabolic costs. The video examines the trade-offs that lead different species to give up the power of flight in favor of different survival strategies.
