The smallest eggs in the world belong to hummingbirds. These nitty-gritty eggs are about the size of a Tic Tac and weigh less than a gram. The exterior of a hummingbird egg is smooth and glossy with a white or pale blue color.
You can usually see small brown spots on the egg, which are where the blood vessels connect to the shell. If you’re lucky enough to spot a hummingbird nest, you may be wondering what the eggs look like.
Hummingbird eggs are very small, usually no bigger than a jellybean. They are white or pale blue in color and have smooth surfaces.
The female hummingbird will lay two eggs at a time, and incubate them for about two weeks before they hatch. After hatching, it will take the young birds another three to four weeks to fledge (grow their feathers and learn to fly).
So if you see a tiny nest with two little eggs in it, be sure to watch from a distance so as not to disturb the parents or the fragile babies.
