Composition on the topic of humans and birds, please solve it

There was once a photographer who went into the forest to look for the most beautiful birds. He wanted to use his camera to show people the most beautiful birds in the world. He asked himself to surpass his predecessors and have maximum close contact with birds.

A few days later, he stumbled upon his target.

How should I describe that bird? It had a long tail and colorful feathers. At that time, it was looking for food. The photographer knew from his own experience that it was a pheasant, but he had never seen such a beautiful pheasant. He hid quietly behind the bushes and watched it. When the pheasant left, he followed it. Then, he started to spread food to the pheasants face to face, but it didn't go well at the beginning. As soon as the pheasants saw someone, they ran away as fast as possible. Fortunately he knew where the pheasant's nest was. The second time, he imitated the bird's call and scattered grain to it. This time it worked, it ate a few pellets, but soon ran away again.

The days passed like this. Half a year later, the photographer successfully became familiar with the pheasant. He took photos of pheasants from various angles and postures. He even became friends with the pheasant, so much so that he could gently stroke the pheasant's head and feed the pheasant delicious food with his own hands. Sometimes, the pheasants will peck at the camera lens.

The photographer left with his camera and video camera satisfied, bringing beautiful pictures and images to people.

The tragedy happened two weeks later. A biologist came that day, and he was planning to make a specimen of a pheasant. While he was lying under a tree sleeping, he suddenly felt his legs were so itchy. He opened his eyes and was surprised to find an incomparable pheasant standing in front of his legs! He slowly stretched out his hand towards the pheasant, but the pheasant still pecked his fingers and blinked. The biologist was a little stunned, but he couldn't control it anymore. He suddenly grabbed the pheasant by the neck.

The pheasant struggled. It could not understand what happened suddenly, but its struggle became weaker and weaker. Finally, the biologist strangled the pheasant to death.

He held the pheasant in his hands blankly, confused - how could the bird be so bold?
