Vagn F. Flyger

Vagn F. Flyger (14 January 1922 – 9 January 2006) was a Danish-American wildlife biologist and one of the world's foremost authorities on squirrels. His landmark work was ''The 1968 Squirrel "Migration" In The Eastern United States''. Flyger was also one of the first wildlife biologists to utilize tranquilizer guns in the 1950s when they were first introduced. In the 1960s, he experimented with dart guns in the Arctic on seals, whales and polar bears. However, seeking a field of study that kept him closer to home, Flyger focused most of his remaining research on squirrels. Provided by Wikipedia
