Compare with the domestic hen and the duck
The domestic hen and the duck both belong to the bird category. They have some features in common such as wings, feet, beak, flight, nest, migration, food and eggs.
The domestic hen has short wings which it rarely uses because it has a heavy body and lives on the ground. It is clumsy in flight and can cover only short distances. Its feet are designed for scratching the ground to find seeds and worms. It will also eat almost any other kind of food. Hens nest on the ground. They have been bred for egg production and can lay up to 300 eggs a year.
A duck has webbed feet so that it can swim easily and walk on soft ground. It has a long, flat beak which it uses to search for food in river and pond mud. It has powerful wings which enable it to fly long distances. It nests in grass at water’s edge. Ducks migrate long distances. A duck lays 5 to 12 eggs at a time and may lay twice a year.
In conclusion, although there are something different among these two birds, the basic features are quite similar.
