They are more likely to eat less ripe green acorns, reducing the amount of food the red squirrels can eat as they eat ripened acorns
Why do trees in the rainforest have low branches?
So they can put all of their energy into upward growth to reach the light fastest
Who do Epiphytes grow on the sides of trees in rainforests?
