Ruby-Throated Hummingbird

7 cm, 3 grams, 65 km/h and 70/sec

7 cm long, weighs 3 grams, flies at speeds of 65 km per hour and beats its wings 70 times a second. The Ruby-throated hummingbird, that is.
Its heart beats 20 times a second when flying and eats half its weight in sugar every day. The elephant heart beats once each 2.5 seconds.

Ahh, guzzling nectar like there’s no tomorrow… here’s to a good week.
