Today at the Raptor Center students learned about the pesticide DDT. DDT was used in the U.S. between the 1940's & 70's to control mosquitoes. Unfortunately it had very negative impacts on birds at the top of the food chain. DDT weaken the shells of birds eggs to the point where they would break when sat on by their mothers.
Students conducted an experiment today to measure the strength of chicken eggs, which are similar in size to Peregrine Falcon eggs. In the experiment students predicted the amount weight an egg could hold. In the end the egg we tested held just over 60lbs, a far cry from the 2lbs of a mother Peregrine Falcon.
