What the species of birds that cannot fly?

Did you know that not all birds can fly? There are three species of birds that cannot fly, namely the ostrich, cassowary and emu.

Actually, there are still many types or species of birds that cannot fly. However, this article only discusses three bird species.

Even though birds are animals that have extraordinary flying abilities, these three bird species cannot fly due to various factors such as body weight and weak wing bones.

The ostrich is a large bird that is usually found in the deserts of Africa. Ostriches have a body size that reaches two meters and weighs up to 150 kg.

However, ostriches cannot fly because their bodies are too heavy, and their bones are not strong enough to support their bodies in the air.

However, ostriches have the ability to run very fast, with speeds reaching 70 km/hour and can cover distances of up to 16 km at the same speed without stopping to rest.

The next bird that cannot fly is the cassowary. The cassowary is a large bird that you can find in Australia and Papua Islands.

This bird has a body size that reaches 2 meters and has pitch-black feathers that cover its entire body. Cassowaries cannot fly because their wing bones are short and weak.

The last bird that cannot fly is the emu. The emu is the second largest bird in the world after the ostrich.

This bird is usually found in Australia and has a body size that reaches 1.5 meters and weighs 60 kg.

Emu birds cannot fly because their wings are too small compared to their large body size.

Even though they cannot fly, these three bird species have other abilities, such as running at high speed and remaining an important part of the ecosystem where they live.
