In golf, the names bogey (+1), par (E), birdie (-1), eagle (-2), albatross (-3) and condor (-4) were used in the score system. I know bogey comes from the song 'Here Comes the Bogey Man', but I'm intrigued why eagle, albatross and condor were used instead of other birds.
In 1800's American slang 'Bird' meant good/excellent so a 'birdie' was a good score. An eagle was most likely just a continuation of the bird theme ( or used for 2 under because it's a bigger bird ). And and albatross ( 3 under par ) is a rare score and an albatross is a rare bird or because they are even bigger than eagles. I've never heard of a 'condor' as a score but then again i've never scored under a birdie. But i just googled it and they are the largest birds in the western hemisphere so it would follow the theme.
Source I've also read 2 of those books they're referencing on that site back when my dad was teaching me to play as a kid.
