The kingfisher is a type of bird known for its small to medium size and brightly colored feathers. These birds can be found all over the world, with the majority of species found in Eurasia and Australia.

While most kingfishers are short and fat, with a body length of about 15 cm and a body shape similar to a woodpecker, there are variations in shape and size among different species.

Kingfishers are known for their big heads, small bodies, and hard-beak shells. Their beaks are long and straight, with horns and sharp ends that allow them to catch their prey quickly. The feathers on their bodies are predominantly bright blue, and while they have short tails, they are incredibly agile flyers. Kingfishers are also known for their sharp, loud, and monotonous calls.

There are two main types of kingfishers: those that dwell in forests and those that live in aquatic environments. Forest-dwelling kingfishers feed mainly on insects and stay out of the water, while aquatic species can be found in ponds, swamps, and streams, and mainly feed on fish, shrimp, and insects.

Kingfishers often perch on tree branches near the water's edge or quietly on leaves in the water, keeping their eyes fixed on the surface until they spot their prey. They then fly straight to catch their food at lightning speed before returning to their perch to wait for their next meal.

Kingfishers often dig holes in earth cliffs near the water or on sandy slopes to create their nests. These nest chambers are spherical and have a diameter of about 16 cm. The nests are lined with fish bones and fish scales to provide a comfortable environment for their offspring. Kingfishers lay their eggs in the spring and summer, and each nest can hold up to 4-5 eggs. These birds are also known by various names like "fish tiger," "water dog," and "fish dog," because of their fondness for fish.

Kingfishers are known for their beautiful and colorful feathers that emit iridescent light under bright light. Unfortunately, the beauty of these feathers has led to the hunting of kingfishers in large numbers. In the past, the feathers of a dead kingfisher were used as decorations in imperial costumes and queen crowns because of their radiance and shine.

However, to capture the most beautiful state, the feathers of live kingfishers were often cut off, leading to their death. To protect these birds, people have started using blue satin ribbons instead of real kingfisher feathers for making jewelry, which is almost indistinguishable from real feathers and more environmentally friendly.

The kingfisher is small to a medium-sized bird known for its brightly colored feathers and impressive hunting skills. While they are known for their beauty, their feathers have also been a cause of their danger.

To protect these birds, people have started using alternative materials for making jewelry that is almost indistinguishable from real feathers. As a result, the traditional gold and silver jewelry-making craft of the Han nationality has been preserved and continuously improved over time, resulting in the creation of unique and beautiful pieces of jewelry.
