Japanese Golden Eagle Q&A
.webp?alt=media)
What kind of eagle is the Japanese golden eagle?
The Japanese golden eagle is a subspecies of the golden eagle and is a National Natural Monument unique to Japan. It is one of the most powerful birds of prey, possessing sharp talons and beak, and excellent eyesight.
They are often referred to as "kings of the sky" due to their strength. They reign at the top of the ecosystem in the mountainous regions of Japan, playing a crucial role.

What do Japanese golden eagles eat?
Japanese golden eagles primarily prey on hares, copper pheasants, and snakes. They sometimes even attack animals larger than themselves, such as foxes, raccoon dogs, and monkeys!
They also eat carrion in the winter when food is scarce.

Where do they raise their young?
Japanese golden eagles build large nests on cliffs. The nests are made of branches, leaves, and grass, and are very large and sturdy.
Females usually lay 1 to 2 eggs, but it is rare for both chicks to fledge. In most cases, only one chick survives. This is thought to be due to food shortage or sibling rivalry.

Why are they endangered?
Since the 1960s, the population of Japanese golden eagles has declined sharply, putting them at risk of extinction. The main reasons for this are as follows:
・Habitat destruction due to deforestation and development
・Collision accidents with power lines
・Lead poisoning
Lead poisoning occurs when eagles ingest lead bullets left in the carcasses of animals shot by hunters. Lead accumulates in the eagle's body and has adverse effects on the nervous and digestive systems.

[Quiz!] How fast can a Japanese golden eagle fly?
In level flight, Japanese golden eagles can reach speeds of 30 to 45 miles per hour (50 to 70 kilometers per hour), and when diving, they can reach an incredible 185 miles per hour (300 kilometers per hour)! This is faster than a bullet train! The speed at which they capture their prey is truly breathtaking.

[Quiz!] How good is the Japanese golden eagle's eyesight?
Japanese golden eagles are said to have vision about eight times sharper than human vision! They use this exceptional eyesight to spot small prey from high in the sky, even from great distances. For example, they can spot a hare from over half a mile (1 kilometer) away.

[Quiz!] What can we do to protect the Japanese golden eagle?
To protect the Japanese golden eagle, it is important to conserve their forest habitat. Measures to prevent collisions with power lines, such as modifying the design of power lines or installing markers, are also necessary.
Furthermore, there is a growing movement to regulate the use of lead ammunition to prevent lead poisoning. Each of us should learn about the current situation of the Japanese golden eagle and think about what we can do to protect them.
