the migratory path of birds from their nesting sites to their wintering sites and back again. The flyways of different bird species or different populations of the same species may vary. Sometimes the spring route differs from the route in the fall. Since birds use the ecologically most favorable routes, the migratory paths of many species frequently coincide. The physicogeographical features of the territory above which the flyways pass and the similarities in the ecological requirements of various species often result in common routes, in which the birds are particularly numerous. Formerly, only such widely used sections of the migratory routes were called flyways. In the remaining sections, the birds, as a rule, fly in a broad front.
