Foreign Birds Animals:
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 animals finches.Nests are generally structures built by animals as a protection for themselves and their young and around which the home life is often centered. To many persons the word "nest" is instantly associated with birds, but numerous mammals, fish, batrachians, reptiles, and invertebrates excel in nest building. Mammals.—Nest building is much less fre¬quent in mammals than in birds. With many of the mammals, the young are able to move about directly after birth, as are the ungulates or hoofed animals.

Another basic problem to which work on game birds has contributed is the analysis of population cycles. The ruffed grouse and some other game birds are subject to violent, more or less regular, fluctuations in population. Deter¬mination of the causes and nature of these cycles has proved to be a surprisingly difficult and baffling problem and one that is far from solved. It is uncertain to what extent epidemic disease is involved and some ornithologists are investigat¬ing the possible role of deficiencies in such hor¬mones as ACTH and cortisone. Darwin admitted the difficulty of determining the factors that con¬trol the numbers and the distribution of many species. The efforts of game technicians to in¬crease the numbers of game birds by experiment¬ing with changes in the environment are of im¬portance in understanding these basic problems regarding animal populations.For the U. S., or Union, government the ma¬jor diplomatic problem of the Civil War was to prevent foreign birds problem recognition, particularly by Brit¬ain and France, of the Confederate States as an independent nation. President Lincoln's govern¬ment wanted to isolate the war, deny the .Con¬federates foreign birds problem help, gain international acceptance of a naval blockade of the South's coastline (proclaimed on May 19, 1861), and forestall foreign birds problem intervention. The Confederacy's goal was to win foreign birds problem recognition, mainly through European intervention in the war itself.

Cats and Birds. There is no question that cats do stalk and kill birds, but cats are an insignif¬icant factor in overall bird mortality. To cite two of a number of biological studies of the stomach contents of cats, only 6 of 50 cats in Wisconsin had eaten birds as their last meal, and birds provided a final repast for only 4% of a group of cats in Oklahoma. Wildlife authori¬ties insist that other birds—jays, for example-kill more birds than do cats. Moreover, cats are themselves the prey of some birds, like the great horned owl.Cat food—Twice daily; offer meat-gravy mixture, meat gravy mixed with potatoes and some cooked meat; prepared canned cat food may be used instead, contains all essentials. Milk— Fresh daily. Vegetables—Essential; must be cooked; give any pet likes. Water—Essential; must be clean, fresh, and available at all times. Fish—May be raw or cooked; give any pet likes. Meat—Raw meat diet alone often causes form of indiges¬tion commonly called "fits." THERE are numerous varieties of birds which are suitable for cage life in either the school or the home. Many species become gentle and permit, even coax for, a certain amount of petting and handling. Some of the most attractive and interesting birds for cage life are the foreign birds rly birds, the greater number of which come from Africa and Australia, although equally interesting pets come from our do¬mesticated birds and from our native wild birds.
