Depending on how far birds can move relative to their habitat, they can be divided into sedentary, nomadic and migratory. Settlement is typical for birds of subtropical and tropical zones, where there is no vital need to fly somewhere. It’s always warm and satisfying here. In migratory birds, movement is determined by seasonality and related breeding patterns.
Nomadic birds are in constant search of food and more suitable weather conditions for life. Such movements are not characterized by cyclicity, they do not depend on the time of year.

Other nomadic birds
Nomadic birds do not fly far from their usual habitat conditions. They can move along the coasts if the food for them is marine inhabitants; in the mountains they change their altitude position, escaping from the cold; wander from the forest to the city in the spring, if there is not enough food in the forest.
The listed birds are typical for the territory of the north and middle zone of Eurasia, which are located in the temperate and subarctic zones. They wander from place to place, driven by exceptionally cold winters and lack of food. If such birds are regularly fed, they can be called sedentary, since they will have no reason to fly away.
