Forkbirds

Question: Which forkbird is the most efficient eater?

IV: Time

DV: Number of Types of forkbirds

Hypothesis: If we test different types of frokbirds, then the 4-tine forkbird would be the most efficient method because with the more tines you have, the easier it is to retrieve more Birde-os at once.

DSET: My claim is that the 4-tine was the most efficient eater, and our prediction was correct. When we did the experiment, the 1-tine forkbirds started off being a population of 6 in generation 1 and then went down to 1 in generation 5 and then back up to 3 in generation 10. For the 2-tine forkbirds, in generation 1 there were 10 forkbirds alive, then in generation 5 there were 4 forkbirds alive, and there were 7 forkbirds alive in generation. Th difference is, is that the 4-tine forkbirds numbers went up rather then down. In generation 1, the population of forkbirds started at 6, then in generation 5 went up to 17 forkbirds who were alive, then in generation 10 there were 12 forkbirds. Using the information from the experiment, you can see that the 4-tine forkbird is the most efficient eater because it retrieved the most bird-e-os in each generation and the population of forkbirds went up every generation. The 4-tine was the most efficient eater because when we tested this experiment using the 1-tine, 2-tine, and 4-tine forkbirds,we found out that with the more tines it had, the easier it would be to retrieve the bird-e-os at once. Also, because of the shape of the the forkbirds beak, it was easier to get the bird-e-os for the 4-tine bird, rather then it was for the 1 and 2-tine birds.

4. I think the new food source (blueberries) will affect the forkbird population by making it decrease by a lot. There is a lot of deforestation now, and in the future there will probably be much more. Since the blueberries grow on bushes and forest plants, there would no longer be any blueberry bushes since they would all be cut down. This causes even more competition among the birds. Since the blueberries are the main source, so many forkbirds will be trying to retrieve the food, and there would be so much competition that some forkbirds might go hungry. If that is a repeating pattern than many forkbirds would die of starvation.

5. I think that NATURAL SELECTION is when the different birds where born to eat different foods based on the shape of their beak. For example, if a bird is a carnivore, it will eat meat, because that's what it was born to do. It's natural.
