Alpha-chloralose: Current status, restrictions and future uses for capturing birds


In 1992, the Animal Damage Control (ADC) program received approval from the Food and Drug Administration (FDA) to use Alpha-Chloralose (A-C) nationwide for capturing waterfowl (Anatidae), coots (Fulica americana), and pigeons (Columba livia). To review the first year (1993) of operational use of A-C, we surveyed in January 1994 all ADC State Directors on the status of A-C use within their states. In 1993, 59 ADC personnel were trained and certified in the approved uses of A-C and 696 nuisance waterfowl were captured with A-C in 10 states. Restrictions imposed by U.S. Fish and Wildlife Service (FWS) and state permits regarding "incidental take," relocation, and euthanasia were responsible for the minimal use of A-C in 1993. Meetings were held in September 1993 and January 1994 to address: 1) the problems with FWS permits; 2) plans for future approved uses of A-C for additional species; 3) the availability of A-C to personnel and agencies outside the ADC program; and 4) provisions for nonapproved uses of A-C (special, emergency and non-emergency situations).
