Video: See a Baby Hummingbirds Beating Heart!
|Ruby Throated Hummingbird mother feeding baby allows us to see its beating heart.|
You can not count as fast as this precious little Ruby-Throated Hummingbird fledgling's heart beats in 40 seconds of video. Watch the zoomed-in PIP of the birds heart area in full 1080 HD. Hummingbirds have the fastest heart rates of all birds. We rescued a prematurely fledged baby hummingbird that crashed and exhausted itself - more on that in later video blogs - but here it is re-united with its mother and in assuming the out of the nest feeding position so the mother can get food into its beak, the bird allows us to see its tiny heart beating incredibly fast under its pink breast flesh. The hummingbirds has one of the biggest hearts in proportion to its body in the animal world, but it is still smaller than a green pea!
