A hummingbird's heart beats 1,200 times a minute 

In flight a hummingbird's heart can hit around 1,200 beats per minute and its wings blur at 50-80 beats per second. To survive the night they drop into torpor, slowing everything to a near hibernation.

Their pink comes entirely from carotenoid pigments in the algae and brine shrimp they eat. A flamingo on the wrong diet slowly fades back to pale white.
