Animal Studies
Animals are wonderful. If you look closely at how they live, you will find many surprises. It is hard to look closely at insects, because they are very small. Plus, many of them fly away when you come near. But if you have a chance to watch them, you will discover how they live. Watching animals is a job that scientists do, called making observations. They have learned a lot about animals.
Scientists learn about tiny animals, and they have studied insects. They found that insects have tools, and they use those tools to survive. For example, they learned about the sawfly. This is just one animal they have studied.
They call it the sawfly because it possesses a kind of saw. It's not a real saw, but it resembles one, and it works like one. It is actually a part of the sawfly’s anatomy. The sawfly uses the saw to make places where the eggs will be safe. It saws at plants in order to create a space where eggs can go. Afterward, the sawfly does something very special. It makes a sort of homemade glue that fastens the eggs where they are laid. We are not exactly sure how it does that, but if you can watch the sawfly you will see this happen.
Some insects have cutting instruments that work in a similar way as scissors. The poppy-bee is one of these insects. It is a bee that makes its home in wood. This bee has a boring tool, and it uses the tool to bore into old wood. It looks like a tool that a carpenter might use. Carpenters make things out of wood, and like carpenters, poppy-bees makes their nests out of wood.
In addition to insects, scientists observe birds, too. They have studied birds using their bills in order to get what they need. Some birds use their bills to cut into wood. They have sharp bills, and are able to cut a hole in a tree. So, they will use their sharp bills to drill a hole to get inside the tree where insects live, and then they eat the insects.
Every animal is amazing. Even dogs and cats can surprise you. The more you observe animals, the more you will learn. Nature is full of surprises. Every part of every animal has a purpose. Scientists learn more about them every day. Nature is a wonderful part of our world.
