Eagle
A score for one hole that is one under par is an, "Eagle".
A birdie is one stroke under par on a given hole.
It means the player shot 4 stokes under par. A par 72 course gives him/her a score of 68 for the round.
Every hole has a par rating - usually 3, 4 or 5. One under means one less than this. So on a par 4 hole a score of 3 is one under par. This is called a birdie.
An albatross is scored in golf when the player completes a hole in a score 3 strokes under par.
The score would change by increasing 6 strokes - like from -1 to +5. For instance, if the golf course was par 70, 69 would be one under and 75 would be 5 over par. Remember, in golf the lower the score the better. Making par for 18 holes is very difficult for most golfers. Berney Trembly
Yes the PGA record for lowest score in one round is 13 under or a score of 59.
A "birdie" is not a specific score, it's one under whatever par for the hole is. If it's a par 3 hole, then a birdie is 2; if it's a par 5 hole, a birdie is 4.
Four (4) same as usual one under par
