How does the osprey fish?

Osprey, the scientific name is cormorant, and some places are called black crow. Feathers are generally black, with purple-green luster on the head and neck, yellow-green on the corners of the mouth and throat sac, white under the eyes, copper-brown on the shoulders and wings with metallic luster, dark copper-blue on the feather edge, round tail, white silky feathers on the head, inconspicuous feather crest on the back of the head, and emerald iris. Very beautiful! Cormorants are good at swimming and diving. When diving, they jump out of the water first, then turn over and enter the water, with beautiful posture. When hunting, cormorants stick their heads into the water to track fish, and their wings have evolved to help them paddle in the water. Cormorants have very sensitive vision and hearing, which is very helpful for their hunting. No matter how flexible the prey is underwater, the osprey will inevitably stretch its neck and make a fatal blow with its sharp beak.

In the southern water town, fishermen often take domesticated cormorants with them when they go fishing. Cormorants stand neatly at the bow, each with a collar around its neck. When fishermen find fish, they whistle and cormorants jump into the water to fish. Because of the collar, the cormorant caught the fish but couldn't swallow it, so it had to return to the boat with the fish in it. After the owner took the fish, the cormorant dived into the water to fish again. When you meet a big fish, several cormorants will catch it together. Some of them peck at the fish's eyes, some bite the fish's tail, and some bite the fish's fins, which is very tacit. After fishing, the owner took off the cormorant's collar and gave them the prepared small fish to eat. This fishing method is very interesting and effective.
