Hummingbird Nests Are As Small As A Thimble And Have The Highest Mass-Specific Metabolic Rate

Hummingbirds are birds native to the Americas that make up the Trochilidae biological family. Many species measuring 7.5-13 cm (3-5 in) in length are the smallest of birds. Several species of hummingbirds are endangered. They are completely tiny, fragile birds are just a few inches long and their eggs are smaller than a jelly bean.

“Hummingbird eggs are tiny, about the size of jelly beans! Please remember to carefully check for nests before you trim trees and shrubs.’

34 species of hummingbirds (10 per cent) are classified as "critically endangered," which means that over the next ten years they have a 50/50 risk of extinction.

So their survival needs to keep an eye out for their tiny nests while pruning. The nests are normally built on a downward-slant branch, and according to The Hummingbird Project, you can also find them on a branch hanging over running water or open space.

From spider webs, lichen, and plant matter, they build their nests, ensuring they are incredibly delicate. The lichen also does a fair job by keeping their nests camouflaged.

Hummingbirds flap their wings on average from 50-80 beats per second, making them a literal blur to the human eye if you have ever seen the wings of a hummingbird flapping, usually when the video has been slowed down or the hummingbird is landing.

Their metabolism is almost as quick as their wings, and as they eat and use up energy, their weight will change significantly over the day; because of this, they absorb half to 8 times their weight in sugar per day, and the average hummingbird eats 5-8 times every hour, that's a lot of their waking day spent feeding!

About 1200 times per minute, their hearts can beat! If you equate that to the average person whose heart beats about 80 times a minute, that means that the hummingbirds' heartbeats 20 times every time our heart beats once, it's amazing!
