more snakes and fewer birds more snakes and more birds fewer snakes and fewer birds fewer snakes and more birds
I gave my students this multiple choice question: An island has many kinds of birds, no native species of snakes, and few large predators. Brown snakes eat bird eggs. What is the most likely result of brown snakes being released accidentally on the island?

Only one answer is correct among these 4 choices:
- more snakes and fewer birds
- more snakes and more birds
- fewer snakes and fewer birds
- fewer snakes and more birds

Could you tell me which one is correct?

more snakes and fewer birds
