Describe role: Darwin has observed a lot of sea or marine birds on the various islands of Galapagos. Some are very different from thoses he observed on the continent of South America. Others seem not to have changed.He has asked you to collect as much information as you can about these birds and organize this information in the form of a report your team will make to the Research Seminar. He would also like you to propose a reason why certain of these sea birds are so different from their relatives on the mainland. Why haven't some of them changed? On this page you can see a photograph on one on the migrating birds, a Blue Footed Booby.
Background Information: You are to follow the URL's provided below and read the information. From this information you are to prepare your report that you will present to the larger group.
Charles Darwin Foundation with links to many animals, volcanoes, history, island information
Information on Darwin's finches, sea birds tortoise, land lizzards, insects, plant life. (Explore this Terra Quest site carefully. Check out the history link, Darwin's visit, and then evolution. Also explore the links to Wildlife with its various zones where there is much information about the birds, the Checklist for species, and the Atlas for good maps.)
PBS site that has great animal photos and descriptions. Explore the general material at link On the Island, review vocabulary. Procede to the history, geology and wildlife links.

Report: You are to present your report in the form of a research paper to the Research Group (which will be the rest of the class). You are encouraged to use visuals...overhead transparency, photographs, or photos from the web to present your informataion. Each member of your team should have part in the presentation. You should be well organized so that you can present your report withing 10-15 minutes. It is preferred that you not read the report but rather explain what you learned in your own words using an outline. Images from the Internet may be projected on our TV in our room if you have the URL.
You should include in the report: (A chart might be convenient to organize information.)
1. The common name as well as scientific name of the various sea birds found on Galapagos.
2. Which are the endemic birds (those that live on the islands year round) and which ones migrate?
3. How do the endemic inhabitants differ from their relatives on the mainland of South America? Make a list of characteristics that are unusual about these species.
4. Do the migrating sea birds differ from their mainland relatives? Explain your answer.
5. A description of habitat, food sources, where each species is located.
4. Photographs or pictures of the various species. (This can be projected on our TV via a Web link.)
5. A proposal for why the endemic sea bird residents are so different from their mainland relatives.
6. What does mobility have to do with Darwin's Theory of Natural Selection and Evolution?
