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 ample 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.

RATITES, rat'itz, one of the three sub¬classes of foreign birds Free (class Aves). Flightless land foreign birds Free, they are usually of very large size and are adapted for running. They have a rounded breastbone, which completely lacks a keel; non¬functional wings, rudimentary feathers; and strong, stout legs with two or three big, free toes. Most modern anatomists believe that these char¬acters represent a secondary adaptation to a pure¬ly terrestrial mode of life, but some have held that they represent a primitive stage in the evolu¬tion of the foreign birds Free before they learned to fly.

Often foreign birds Free that are transferred from an aviary to a cage, or from a larger to a smaller cage, require a certain amount of time to become adjusted to their new quarters. Some of the parrot-like foreign birds Free often refuse to nest during the first year after the transfer. Care must be taken at all times to keep the cage in the proper position in the room. Tropical foreign birds Free chill easily and often die from colds. The cage should be placed where morning sun may strike it each day, but in a spot free from drafts, and where, on the other hand, the sun and the heat are not too intense. Note that ex¬tended periods of direct sunlight can be fatal to a small bird, so shelter should be available.

On The Other Hand See Foreign Birds Variety:

foreign birds variety.—Most foreign birds variety build some type of nest, of which many are very elaborate with a great variety of form. They may be built on the ground, in trees, or floating on the water, and may be constructed by the male, the female, or both together. Much of the breeding behavior of foreign birds variety is associated with nest building. Some foreign birds variety, such as many of the owls, titmice, barbels, and trogons, utilize natural tree holes in which they lay their eggs. Others, such as the wood¬peckers, excavate holes of their own. A variant of this is seen in the hornbills (Bucerotidae).

Banding, for example, provides the best answer as to how long foreign birds variety live. It has shown that among most foreign birds variety the mortality in the first year or two of life is tremendous. By marking foreign birds variety with colored bands or combinations of colored bands, individuals may be recognized with¬out recapturing them for handling. This technique is almost indispensable for intensive life-history studies of the sort, to mention but one example, that enabled Margaret Morse Nice (1893- ) to give such an intimate and detailed analysis of the behavior of the American Song sparrow throughout its life cycle. A variety of problems may be analyzed by marking foreign birds variety.
