For close to seventy years, the Patuxent Wildlife Research Center in Maryland has had a diverse set of ongoing research projects dealing with wildlife and natural resources in and around the region. Their homepage offers a great deal of material on these projects, along with some very fine information for the general public. The “Spotlight” section is a good place to start as it contains a frog call quiz and video clips of Atlantic sea ducks in their natural habitat. The “Science Features” area contains an area where visitors can ask resident biologists pressing questions and a “Did You Know?” section that provides answers to such questions as “Why are whooping cranes endangered?” The site is rounded out by an area that provides a tribute to Chandler S. Robbins, an employee of the center for over sixty years. Robbins is perhaps best known as the author of “The Field Guide to Birds of North America” and for his work on identifying the deleterious effects of DDT on bird populations. [KMG|
