. Useful birds and their protection. Containing brief descriptions of the more common and useful species of Massachusetts, with accounts of their food habits, and a chapter on the means of attracting and protecting birds. Birds; Birds. VALUE OF BIRDS TO MAN. 55 have both the time and patience to watch the feeding of young birds for an entire day. Dr. C. M; Weed and Mr. W. F. Fiske, however, have accomplished this feat. They watched the nest of a Chipping Sparrow from 3.40 a.m. to 7.49 p.m. on June 22, 1898. Tiie valuable record of these observations. Fig. 25. — Chipping Sparrow feeding young. shows that these two birds, having only three young in the nest, visited it at least one hundred and eighty-two times during that day; and Dr. Weed says that they made almost two hundred trips, although some of the trips evidently were made to furnish grit for grinding the food. The birds were busy from daylight to dark, with no long intermission. The food, so far as identified, consisted largely of caterpillars. Crickets and crane flies were seen, and it was believed that a great variety of insect food was brought. ^ A committee on useful birds, selected from the Pennsyl- vania State Boai'd of Agriculture, reported that an observer had watched the nest of a pair of Martins for sixteen hours, from 4 A.M. until 8 p.m., to see how many visits the parent birds made to the young. One hundred and nineteen visits were made by the male and one hundred and ninety-three by the female.^ ' The Feeding Habits of the Chipping Sparrow, by C. M. "Weed.
