Another simple achievement. To achieve it:
Evil route: Be nice to the bees by giving them flowers in the pot under the hives. This will generate points for the good category, but compensate with other Evil actions. You have to keep being evil to get the Beekeeper title.
Good route:Kill birds and destroy their nests; this will result in points in the Evil category, so compensate with other good actions. You have to keep being good to get the Ornithologist title.
Do one of this two options, and the achievment will pop!
