A good question is, what species made and used the first tools?

Both species are using the former to make great progress with the latter.

Some species may use more than one system depending on the circumstances.

Both species use their long, powerful arms for climbing in trees.

This is probably the reason why many species use their fins or arms for moving if possible.

They must be created by each thinking species using the tools of logic.

Other species will sometimes use these techniques if the opportunity arises.

Ongoing research is constantly finding more effective ways to put the species to use.

Currently, 103 different species of birds use this new habitat.

No fishing is allowed, and many species of bird use the habitat.
