Birds Kept in Captivity

Birds in captivity. When birds are kept in captiv­ity the exact amount and kinds of food eaten may be determined. The kinds eaten, under those condi­tions, however, are not a safe guide for determining the kinds eaten in nature, as doubtless, when hun­gry, birds will eat many things which they do not normally eat when at liberty. More accurate esti­mates may be made of the amount of food eaten, as the bird would doubtless require more food when free than when in captivity, so that the amount eaten in captivity would be a minimum.

Bob-white. The food habits of the bob-white have been studied with birds kept in captivity. Each of the following is a single day's rations: 1350 flies, 5000 aphids, 1532 insects, 600 seeds of burdock, 12,000 seeds of pigweed, 15,000 seeds of lamb's­quarters. The bob-white was found to eat in cap­tivity 61 kinds of weed seeds, besides the 68 kinds previously recorded, making a total of 129 species. It has also been found to eat 135 different kinds of insects.

Approximately one seventh of the robin's food is composed of materials beneficial to man, one third is composed of insects harmful to man, and about one half is composed of neutral elements.

So far more than sixty thousand stomachs, com­prising over four hundred species of birds have been examined by the Bureau of Biological Survey.

Still a fourth method is the combination of field and laboratory work. The birds are studied in the field in those localities where birds are collected for stomach examinations. Facts are gathered relative to the available food-supply for birds; these, in con­nection with the examination of the stomach, show what a bird will eat, what it prefers, and what it refuses.
