The habitat of red-crowned cranes is diverse and complex. They usually choose to inhabit areas with abundant water, abundant food**, and suitable climates, such as swamps, lakes, rivers, beaches, etc. These places are also often a gathering place for birds, as they provide an abundant food resource and a relatively safe habitat. 
In swampy areas, red-crowned cranes especially prefer to feed in shallow waters, where food is abundant and also conducive to their take-off and landing on the water. In lake and river areas, red-crowned cranes tend to roost on the shore or in shallow waters, where the flow is slower and food is concentrated. In beach areas, red-crowned cranes usually roost in tidal flats above the high tide line, where food is equally abundant and it is also good for them to take off and land on the beach. 
In addition to the natural environment, red-crowned cranes are often found in man-made environments such as farmland, grasslands, and parks. These places are often due to human factors that have changed the natural environment, but at the same time provide some food and habitat conditions for the red-crowned cranes. In these places, red-crowned cranes usually forage and roost with other birds, forming an ecological phenomenon that lives in groups. The social life of red-crowned cranes is very interesting. They usually fly in groups to their feeding grounds early in the morning or at dusk, where they forage and roost. These flock-dwelling red-crowned cranes usually have a leader bird that leads the movement with other birds. The leader bird is usually an experienced red-crowned crane that leads other birds in search of food in their feeding grounds and maintains contact with other birds. 
In addition to foraging and roosting, red-crowned cranes also engage in courtship and breeding in these places. During the breeding season, male red-crowned cranes will show their charm in various ways to attract the attention of female red-crowned cranes. Once the female red-crowned crane has chosen her mate, they will start nesting and laying eggs. Red-crowned cranes' nests are usually made of branches and blades of grass, and are very delicate. In conclusion, the habitat of red-crowned cranes is diverse, and they will choose the most suitable habitat for them according to their needs. Red-crowned cranes will have different behaviors and habits in different habitats, which is also a manifestation of their adaptation to the environment.
