What is migratory birds?

The dictionary definition of migratory bird is a bird that travels from one place to another at regular times often over long distances. ... Most native bird species (birds naturally occurring in the United States) belong to a protected family and are therefore protected by the Migratory Bird Treaty Act. Most of our migrating birds fly to south for winter but for example dipper comes from north to overwinter here in Finland. For example hazel hen, magpie, black woodpecker and siberian jay are resident birds: they spend the winter in north. Crow is one of our partial migrants. There are many different migration patterns. The majority of birds migrate from northern breeding areas in the summer, to southern wintering grounds. However, some birds breed in southern parts of Africa and migrate to northern wintering grounds, or horizontally, to enjoy the milder coastal climates in winter.
