This 'relative bird-like way' makes no sense at all. Humans are not birds. They are not even related. They are completely different organisms.
Humans have had zero evolutionary pressure for minimizing energy expenditure while in hovering flight.
Birds had more than 150 million years to optimize their benefits for survival and reproduction [1,2]. They even survived the Cretaceous–Paleogene extinction event [3] where the evolutionary pressure of food scarcity was at an extreme.
