The term migration describes large-scale periodic movements of birds, and the only way to consider migration is to look at the distances traveled during their migration.
Definition of bird migration
Birds that live in the northern hemisphere tend to migrate north in the spring to take advantage of the numbers of thriving insects and emerging plants present in nesting sites, with the approaching winter season and the availability of insects and other foodstuffs, the birds move south again, and escape from the cold is a catalyst and essential factor except Many species, including hummingbirds, can withstand freezing temperatures as long as there is enough food.
Climate impact on bird migration
Migration can be caused by a combination of climatic changes throughout the day, low temperatures, torrential rains and winds, as well as changes in food supply and genetic preparation.
For centuries people who kept cage birds observed that migratory species go through a period of insomnia every spring and autumn according to climate changes and repeatedly flutter toward the side of their cage, and German behavioral scientists gave this behavior the name of migratory strained birds.
Some species, especially waterfowl, follow favorite paths in their annual migrations, and these paths are often associated with important stopping sites that provide the food supplies necessary for bird survival, and small birds tend to migrate on broad fronts across the landscape, and recent studies have revealed that many small birds take paths Various in spring and autumn, to take advantage of seasonal patterns in weather and food.
The most famous migratory bird
The term immigration describes large-scale periodic movements of animal populations, and the only way to consider migration is to look at the distances covered, and the types of migratory birds can be divided in terms of distance into the following types:
- The permanent resident birds who do not migrate, are able to find an adequate supply of food throughout the year.
- Migratory birds from short distances to a very short distance from highlands to the lower regions at the foot of the mountain.
- Migratory birds with medium distances that extend from one state to several states.
- Birds migrating from long distances usually from the breeding ranges in some places such as the United States and Canada to winter areas such as Central and South America, and despite the arduous journeys involved, long-distance migration is a feature of about 350 species of birds.
One of the most famous migratory birds is quail, hoopoe, wild ducks, curlew, cardinal and gore.
The best times to migrate birds
Migration in the spring and autumn is one of the best times to see many birds, and during migration many types of birds gather in large groups that are easy to see, and birds can also be treated with displaced birds that have become deformed along their migration routes, and depending on the individual path of the species the bird may stop between ranges Reproduction and wintering in areas that make it accessible to birds far from the usual ranges.
