Jack MinerDied 3 Nov 1944 at age 79 (born 10 Apr 1865).Canadian naturalist, author, and lecturer who won a reputation as a leading bird conservationist and who conducted extensive research into migratory patterns. In 1904, he founded the Jack Miner Bird Sanctuary for the conservation of migrating Canada geese and wild ducks, originating the waterfowl refuge management system. In 1909, he pioneered the tagging of migratory waterfowl by banding his first wild duck. The band was returned by Dr. W. Bray of Anderson, South Carolina in Jan 1910, thus making the first complete banding record. The same year Miner started a 30 year lecture career speaking on wildlife conservation and the need for the establishment of sanctuaries and wildlife refuges. |
