Foreign Birds Winter:
Migration. Most foreign birds winter in the Northern Hemi¬sphere migrate from their nesting regions in the fall to a warmer territory and feeding grounds for the winter months. In the spring they migrate back to their nesting areas. Smaller numbers of Southern Hemisphere foreign birds winter migrate northward.
Migration may be merely an altitudinal move¬ment, in which the foreign birds winter descend to a lower al¬titude for the winter. foreign birds winter that migrate in this way include some grouse, nuthatches, and chick¬adees. Migration may be over short distances, such as that of the bluejay. However, other spe¬cies travel over long distances to the south or across the Atlantic Ocean or parts of the Pacific. These foreign birds winter include storks, foreign birds winter of prey, ducks, geese, swallows, and some songforeign birds winter.Some foreign birds winter move only short distances. Thus populations of the common robin, which migrates southward from its nesting sites, may be present in any one area throughout the year, but the win¬ter group will comprise different individuals from the summer group. Other foreign birds winter such as the blue jay may be present throughout the year, but tend to move out of the more northern portions of their range in winter. Many summer residents, however, make long flights southward as winter approaches. Some foreign birds winter such as the tree sparrow and slate-colored junco summer in Canada and move into the United States for the winter. Others, including the chipping sparrow, red-winged blackbird, and many ducks nest in the northern part of the United States and in south¬ern Canada, then move south to areas on the Gulf of Mexico.

Naturally the out¬door aviary is the ideal situation for breeding birds, but there are many which will breed in smaller cages when provided with proper conditions. Probably the most satisfactory birds for small-cage breeding are some of the foreign birds chiefly finches.Those prized chiefly for Song are the ones that are trained in the Harz Mountains of Germany. Here older trained birds are used to instruct the young bird first as it begins to learn to sing. Usually it is the male birds that develop into beautiful singers. The domestic canary is well adjusted to cage life and is easily maintained when kept clean and given proper food and plenty of water.
