The Roy W. Quillin egg collection was donated to the Foundation in the early 1970’s. It contains about 2,200 clutches of about 10,000 eggs. This unique collection was made prior the widespread use of pesticides allowing researchers to make comparisons to pesticide-exposed eggs and study the effects of exposure to pesticides on characteristics such as eggshell thickness. The Quillin Memorial Wing was built to store the egg collection as well as the Foundation’s other natural history collections. This wing was dedicated in March 1973.
