Gone daddy gone, an estimation.
Guiding Question how does global warming affect native birds migrational habits?

Procedure for Investigation look up times of when birds migrate online or in books, and show what times they do on a timeline.

Materials none, other than sources of information.

Hypothesis I think that global warming will indeed affect migrational habits, because most (if not all) birds migrate when it gets too cold for prey to live normally, and have to move to get more food.

Interpretation of Results

The rusults here show that with some species, they might be repoplulating and the babies could be coming earlier, or it could just show that global warming IS in fact affecting the times that they arrive, morso than the times they leave. For others, it would appear that they are not being affected much by global warming, and are just doing what they always have.

Conclusion

my conclusion is that for certain species, global warming has and effect, but for others, it does not seem to do much.
