Satellite Mallard Tracking
You duck hunters may have known about this already, but I just found this site and thought is was neat. From the Arkansas Game and Fish Commission comes Satellite Mallard Tracking Last March, they released 28 ducks carrying transmitters. Now only 7 are alive and transmitting. Several transmitters quit working, several ducks died before they got out of Arkansas last March, several died on the breeding grounds and 1 was harvested in North Dakota. Although they have lost quite a few transmitters, they were still able to gain insight into their migration patterns and breeding areas. In the near future, they will post a complete report detailing the fates of each of the 28 transmitters they released last year. The batteries used in these transmitters have a life of about 12 months so they expect to lose even more before too long.
This February, 53 more transmitters will be deployed and will be tracked on this site.
