An eagle in golf is when you score two under par on the hole. Example: On a par 4 you score a 2 or on a par 5 you score a 3
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.
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.
A eagle in golf is when you score 2 under par on a hole. For example on a par 5 you make it in the hole in 3 shots or par 4 in 2 shots
An eagle is scored when you get 2 under par. EX: Par 4 hole you score a 2. Par 4: 1- Hole in One 2- Eagle 3- Birdie 4- Par 5- Bogey
5 = par 4 = birdie 3 = eagle 2 = double eagle 1 = ace (hole-in-one)
If a hole, say hole 1 is a par 3, par 4, or par 5 then the course is telling you if you hit the ball in the hole in the number par then you are even with par. If you hit the ball in the hole on a Par 4 in only 3 hits then you are one under par or -1 for that hole. If you hit the ball in the hole in 5 hits on a par 3 then you are +2 for that hole. So a Par is hitting the ball in the hole in the estimated number for that hole. Par will always be set at 3, 4, 5
