But in some parts of the world, the longitudes do not change much according to the geomagnetic field. Migratory studies were conducted in the fall with young birds and in the spring with older birds. Studies have shown that time, time, and space-based bird flight techniques are more common in older birds. Researchers have found that the species Freed women traverses the longitudinal line and returns to its native habitat in the spring with two axial air travels.
