Here are some facts about feathers – they’re closer to our hair and nails than you think! What makes them so powerful to be able to lift a whole bird is their structure. They’re light but dense and perfectly layered to protect and benefit the bird.
Hummingbirds have some of the most beautiful feathers among birds. If they frequently visit your garden, you can find a fallen feather once in a while. Their total number of feathers can exceed 1,000 in some cases, but they’re not all the same size.
Read on to learn some surprising facts about feathers.
So what are feathers made of? Feathers contain 80 to 90% keratin, a protein that we can find in human hair, skin, and nails. Unlike other proteins, keratin is highly resistant to tears, scratches, and breakage, which we can notice in our own bodies.
This is one of the most fascinating facts about feathers. If you ever wondered why are feathers so light, it’s all due to the simple composition.
Since keratin is the main ingredient, feathers can endure bad weather, strong winds, and fights. Small species like hummingbird shed their feathers once a year, replacing the damaged ones with a new set. This process is called molding, and larger birds can mold up to twice a year.
How Many Feathers Do Hummingbirds Have
Hummingbirds have between 940 and 1,000 feathers, depending on the type. The feathers are divided into a few sizes, and each has a specific role. Hummingbirds don’t have dense coats since they’re primarily migratory birds and live in warmer climates.
When Do Feathers Appear In Baby Birds
Once the baby birds hatch, they’re naked with no thermal insulation, so the mother is responsible for keeping them warm. The first feathers start appearing 2 weeks later. These are usually the tail and wing feathers. The baby hummingbird’s body is completely covered in 3 to 4 weeks.

Different Types Of Feathers
Feathers and hair might share the composition, but they’re entirely different. Complicated feathers have the central bar called the rachis, which grows branches or barbs. The barbs divide into smaller units called barbules. The finished look is a sleek aerodynamic coat.
Hummingbirds have 10 primary feathers, settled in the outer half of the wing. These feathers are responsible for the forward thrust. Next, they have 6 to 7 secondary feathers located along the arm length and help the bird stay afloat in the air.
The tail feathers, which are 10 in hummingbirds, help with balance and control. They serve both as a steering wheel and a brake.

Feathers And Water
One of the most mistaken facts about feathers is that they’re waterproof. The anatomy of the feathers and their layering protect the bird from different weather conditions like winds and rain.
The softest part, the down, quickly gets wet and heavy, so the outer feathers keep it dry. If hummingbirds get too soggy, they can’t fly, leaving them hungry and an easy target to predators.
So how do birds clean their feathers? The preening is among the most interesting facts about feathers. It’s the bird’s way of grooming, tidying up, and polishing the feathers using its beak.
