Produktbeschreibung
Excerpt from Economic Value of the Starling in the United States There were secured for this investigation a total of 2,466 well-filled stomachs, probably a greater number than has ever before been used for investigating the food habits of a single species of bird. Of these, 309 were of nestlings. Approximately two-thirds of the material was collected by representatives of the Biological Survey, the remainder being secured from reliable collectors, who at the same time submitted many economic notes of interest. Of these stomachs 1,250 were collected in Connecticut, 814 in New Jersey, 269 in New York, 62 in Pennsylvania, 43 in Massachusetts, 27 in Rhode Island, and 1 in Delaware. Besides these there were gathered 160 additional stomachs only partially filled with food. While these were not suited for estimating percentages, they furnished considerable information concerning food items. In response to a circular letter sent under date of June 15, 1915, to numerous bird students, horticulturists, and practical farmers, 269 replies were received. The following questions, embodied in that circular, will give an idea of the data obtained: 1. About what year did the starling appear in your neighborhood? 2. Is it now common? When did it become so? Abundance as compared with other species. 3. Is the bird destructive to fruits? State kinds and, if possible, the approximate amount of damage. 4. Does the starling damage any other crops or property? 5. What are the relations of the starling to other times? 6.Where plenty of nest boxes have been placed, has friction between the starling and other species decreased? 7. At what time of year do starlings begin to flock? Are they more destructive when in flocks than at other times? 8. Does the starling spend the winter in your locality? 9. From your observations do you consider the starling injurious or beneficial? Besides the replies to these requests, correspondence from other sources has yielded many facts that have been incorporated in this bulletin. Distribution And Abundance Of The Starling. The starling (Sturnus vulgaris) is native to all but the most northern parts of Europe, and also occupies the same latitudes in the western two-thirds of Siberia. Migration in fall takes the bulk of the species to countries bordering on the Mediterranean, and a portion to the warm latitudes as far east as Hindustan.
