Foreign Birds Flap: If one of these conditions cannot be satisfied, the flap must be delayed. In this case, all the vessels carrying blood to the skin except those entering through the pedicle are severed in stages by incising along the margins and by undermining the flap in two or more operative procedures, depending on its size and location. When the delay is completed, the blood enters the flap only through the pedicle. Either a flat flap, which is sutured back in its original bed at each stage of the delay, or a tubed flap, which is fash¬ioned by rolling the skin together like a suitcase handle so that the two edges can be brought in apposition, can be prepared. Each type has its indications and uses. The advantage of the tubed flap is that it can be migrated end over end from one part of the body to another.The entrance flap closes by ilself when Ihe bird emerges, and on reluming Ihe bird holds down one side of Ihe flap as it works its way inward. Some of the weaverforeign birds flap (Ploceidae), Ihe bush lils (Psaltri-parus), and Ihe orioles (Icleridae) build hang¬ing nesls. The most striking of these is made by the large orioles of Iropical America, Ihe caciques or oropendolas (Cacicus). These hang¬ing nests are made of dry grasses woven and felted logelher and may be five feet long. A colony of these foreign birds flap will nest together in a single tree. See Also Foreign Birds Worked: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 worked finches.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.
On The Other Hand See Foreign Birds Here: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 here 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.Here again some languages have more elaborate morphological systems than others. To express number, English has two systematic possibilities-singular bird and plural birds—and many that are nonsystematic: two birds, many birds, few birds, a flock, and so on. In classical Greek this section of the morphological system was fuller by one degree: ornis ("bird") and ornithes ("birds"), but also ornithe ("two birds"). Word Order. As inflection disappears from a language, other devices assume its function. Char¬acteristic is the English use of word order.
