What is bird migration?
Bird migration refers to the seasonal movement of birds from one place to another. This movement can be within their breeding range, wintering range or both. Migration is a natural phenomenon that occurs annually, and it involves millions of birds across the world. The distance and duration of migration vary depending on the species of bird involved.
Why do birds migrate?
Birds migrate for several reasons, including seasonal changes in food availability, breeding, and climate. Migration is an adaptation that allows birds to survive in changing environments. For example, birds that breed in the Arctic during summer fly south to warmer regions during winter when food is scarce. Similarly, birds that breed in the tropics move to regions with abundant food during the dry season.
Types of bird migration
There are two main types of bird migration: diurnal and nocturnal. Diurnal migration involves birds that fly during the day, while nocturnal migration involves birds that fly during the night. Some species of birds use both types of migration depending on the circumstances.
Non-migratory birds
Non-migratory birds are those that remain in one place throughout the year. These birds do not undertake seasonal movements like migratory birds. Instead, they establish territories and remain in the same area year-round. Non-migratory birds are usually found in regions with stable climates and abundant food sources.
What birds do not migrate?
There are several categories of birds that do not migrate. These include resident birds, tropical birds, flightless birds, birds of prey, domesticated birds, and urban birds.
Resident birds
Resident birds are those that remain in a particular area throughout the year. They do not undertake seasonal movements like migratory birds, but instead, they establish territories and remain in the same area. Examples of resident birds include blue jays, chickadees, and mourning doves.
Tropical birds
Tropical birds are those that live in tropical regions all year round, and they do not migrate. These birds include parrots, toucans, and various species of hummingbirds.
Flightless birds
Flightless birds are those that cannot fly, and they do not migrate. Examples of flightless birds include ostriches, emus, and penguins.
Birds of prey
Birds of prey are those that hunt for food and do not migrate. These birds include hawks, eagles, and owls.
Domesticated birds
Domesticated birds, such as chickens and turkeys, do not migrate. These birds are usually kept in captivity and are not adapted to migration.
Urban birds
Urban birds are those that have adapted to living in urban environments and do not migrate. Examples of urban birds include pigeons, sparrows, and crows.
Conclusion: Birds that don’t migrate.
In conclusion, while migration is a natural phenomenon that occurs across millions of birds worldwide, there are several categories of birds that do not migrate. These birds include resident birds, tropical birds, flightless birds, birds of prey, domesticated birds, and urban birds. These birds have adapted to living in stable environments and do not require seasonal movements to survive.
