There could be other characters like the animals that the hunter is after. For example, if he is hunting deer, the deer could be considered important characters in a way, as they are the objects of the hunter's pursuit and also part of the natural setting.
Maybe there are other human characters as well, such as fellow hunters or people from the hunter's village. They could play roles in providing context, like giving the hunter advice before he sets out or waiting for him to return with his catch.
Well, obviously the hunter is a main character. He is the central figure around whom the events of the story revolve.
Since I don't know the exact story, it could be the hunter himself as the main character. There might also be the animals he is hunting, which could play important roles even if they don't have as much agency as the hunter.
The main characters in 'The Hunter and the Doves' short story are, of course, the hunter and the doves. The hunter represents the force of destruction or the predator. He is on a mission to capture the doves. The doves are a flock of birds that are in a vulnerable position. They have to think fast and act together to save themselves from the hunter. Their interaction forms the core of the story as it is all about the hunter's pursuit and the doves' attempts to elude him.
The primary character is, of course, City Hunter. He's the central figure who drives the action. Then there are the clients who come to him for help. They can be damsels in distress or businessmen in trouble. And don't forget the villains. They are usually powerful and cunning, which makes City Hunter's job more challenging.
It might be about the relationship between man and nature. The hunter's experiences during the day could show how he interacts with the natural environment, whether it's hunting for food or facing the elements.
I don't know for sure as I haven't read it, but there's likely to be the hunter himself. There might also be other characters like people in the hunter's village who support or oppose his hunting activities, or perhaps other hunters he meets during his journey.
In 'A Day in the Country' short story, there might be a family living in the countryside as main characters. For example, a father who works on the land, a mother taking care of the household, and their children who are full of curiosity about their surroundings. There could also be an old man in the village who is like the storyteller, passing on the local lore and wisdom. Or perhaps a young couple who have come to the country for a day trip and their experiences form part of the story.
As I haven't read the 'the day of silence short story', it's impossible to name the main characters. However, if it's about a family, the main characters might be the family members who each have different reactions to the day of silence. Or if it's in a workplace setting, it could be the employees and their boss, all dealing with the silence in their own ways.
Since it's a story about hunters, the main characters would probably be the hunters. There might be an experienced hunter who leads the group, and some younger or less experienced hunters who are learning from him. There could also be a character who has a different view on hunting, like a more conservation - minded hunter among those mainly focused on the kill.
Since I don't know the story, the main characters could be a prophet - like figure who warns about Judgement Day, and the skeptics who don't believe him until it's too late. There might also be a group of leaders trying to maintain order during the chaos.
I'm not sure exactly who the main characters are without reading the story. But it could be a young boy or girl who is excited to explore the fair. Maybe it's an old man who has memories associated with the fair from his youth and is revisiting it.
