Golf has several scoring achievements that are extremely difficult to make. A birdie is one stroke under par, while an eagle is two strokes under par. An albatross golf , also called a double eagle, is three strokes under par and is much rarer. For example, making a 2 on a par-5 is an albatross. A condor, which is four strokes under par, is even rarer. These scores are special because they require both excellent skill and a lot of luck.
