Kingfisher
Birds of the genus Kingfisher are medium-sized water birds. It is commonly known as the kingfisher because of the bright blue feathers on its back and face.
The following is an introduction to the kingfisher from several hair aspects.
Habitat
The kingfisher inhabits small rivers, streams, lakes, and irrigation canals where there is forest and water which is clear and slow flowing. They are solitary and usually perch alone on branches or rocks near the water's edge, waiting for an opportunity to hunt. They usually eat small fish, crustaceans, and a variety of aquatic insects and their larvae, as well as tiny frogs and a few aquatic plants.
The kingfisher can maintain excellent eyesight once it has entered the water, as its eyes can quickly adjust to the contrast in perspective caused by the light in the water. This is why it is such a good angler.
