Every country has its own iconic symbols of unique significance, such as national emblems, national flowers, national treasures and famous cities or buildings.

Many people think of China when they think of pandas.

The bald eagle is actually a white-headed sea eagle, also known as the American eagle. It is a relatively large and fierce bird of prey, with adults reaching a height of one metre and reaching two metres on the wing. The main part of the eagle's body has dark brown feathers, while the eyes, beak and feet are pale yellow, and the head, neck and tail are white.

They are beautiful and majestic to look at and inhabit areas such as coasts and rivers, where they have a great ability to fly. They feed daily on larger fish such as salmon and trout, as well as birds such as ducks and gulls. The eagle's beak is very sharp and can tear its prey to pieces in a very short time. It is also a highly representative species of the Americas.

On 20 June 1782, the United States Congress voted to make the Bald Eagle the national bird of the United States, before they became endangered.

There were only a handful of Bald Eagles in existence at the time, but the American population was gradually boosted by artificial breeding assistance. Typically, the Bald Eagle lays two eggs in a clutch, and the young are chestnut brown in colour, with no white feathers on their heads or tails. It takes only four months for these young to grow to the same size as the adults, as the immature blad Eagles have longer tail and wing feathers and appear to be larger, but still do not weigh as much as the adults.

The eyes of adult Bald Eagles are large and have raised brow bones, which look very aggressive, but actually serve to protect the eyes. With their radar-like eyes they can spot their target prey and swoop down quickly, and they can fly at speeds of up to 70km/h, catching their prey in the blink of an eye with hooked beaks and sharp claws.

The blad eagle's sharp, knife-like claws are its most powerful weapon, and the underside of its claws are as rough as sandpaper, which allows the blad eagle to hold on to fish and snakes, its slippery-bodied prey.

During the annual salmon run in Alaska, USA, just over 10 kilometres of riverbank can attract thousands of blad eagles, which make a seagull-like squawking sound to call their kind to come and eat the salmon. In fact, they are so clever that when they are looking for food they will not only look for themselves, but also look around to see which direction the other eagles are in.

When many of them are circling around an area, they know there is food when all the eagles within a 60km radius can see the circling group. In this way, the bald eagles can have a meal without any effort.
