Abstract: From 1961 to 1969, some 148 compounds were tested for immobilization of red-winged blackbirds (Agelaius pheoniceus) and Starlings (Sturnus vulgaris). Of these, 25 showed enough promise to warrant advanced testing on sever additional species of wild birds: the common grackle (Quiscalus quiscula), common pigeon (Columba livia), house finch (Carpodius mexicanus), house sparrow (Passer domesticus), mallard duck (Anas platyrhynchos), ring-necked pheasant (Phasianus colchicus), and yellow-headed blackbird (Xanthocephalus xanthocephalus). Although no single compound was best suited for immobilizing all of the nine species tested several compounds possessed exceptional activity on three or more of the species tested. Of the species tested, redwings and house finches were the most sensitive to immobilizing agents and pheasants the least. |
