For example, the stomach of one yellow-billed cuckoo contained 250 tent caterpillers, that of a nighthawk 500 mosquitoes, that of a cedar waxwing (cherry bird) 100 cankenvorms. The crop and stomach of a red-winged blackbird were found to contain 1800 seeds of ragweed, that of a bobwhite 5000 seeds of pigeon grass, and that of a mourning dove 9200 seeds of pigeon grass. These figures represent single meals of the birds in Fig. 12.— "Young birds require even more food tJian old ; Louisiana water thrush feeding its young probably consumed where the food was very abundant, as it is in the case of insect outbreaks or where weeds have become troublesome. Obser- vations made in the field are no less convincing, and corroborate the laboratory studies. We find recorded a scarlet tanager which devoured 630 gypsy moth caterpillars in 18 minutes — a rate of 2100 in an hour. A Maryland yellow-throat consumed 3500 plant lice in 40 minutes — a rate of 5250 in an hour. Young birds require even more food than do old birds, as any one who has watched young birds being fed in the nest will testify. The quantity of food that they require increases with their age, reaching a maximimi at about the time they leave the nest. Many nests have been watched by persons interested, and the number of times that the young were fed recorded. A family of young martins was fed 312 times in a single day,.
