how many times does a hummingbird heartbeat per minute
Hummingbird With the exception of insects, hummingbirds while in flight have the highest metabolism of all animals â€“ a necessity to support the rapid beating of their wings during hovering and fast forward flight.[3][33] Their heart rate can reach as high as 1,260 beats per minute, a rate once measured in a blue-throated hummingbird, with a breathing rate of 250 breaths per minute, even at rest.[34][35] During flight, oxygen consumption per gram of muscle tissue in a hummingbird is about 10 times higher than that measured in elite human athletes.[3]
