The Ancient Mariner achievement was much harder to get than the Screaming Eagles achievement, yet the latter awards 10,000 Units while the former gives only 1,500 Units. Isn’t commensurate with difficulty.
Also there should be some sort of achievement for condors too. I was really surprised when I got my first one and there wasn’t any achievement, even for getting X of them.
I legitimately saw that and began scrolling through this page to see if someone one beat me to it. 
, but yea considering it’s significantly harder to get albatrosses, it should be worth at least 20k units
