An eagle is when you finish a hole of golf in two under par. For instance, if the score card says a good golfer should make a five on a hole and you make a three, it is an eagle. An eagle on a par three would obviously be a hole in one, but it would be referred to as an eagle for scoring purposes. Unfortunately, an eagle usually only pays the same as a birdie on the bet (double), but it is a treat for most average golfers, who might only have one a year.
