"Merlin will be a new kind of bird identification tool-one that combines artificial intelligence with input from real-life bird watchers to produce an online "wizard" that helps people ID birds quickly and connects them to more information. To build Merlin, we need to know how thousands of people remember and describe birds. You can help us by playing games that gather the information to help Merlin understand what bird watchers see. The more you play, the more you'll help Merlin become a true bird ID wizard."

"Streamer is an online map service that lets anyone trace downstream along America's major rivers and streams simply by picking a point on a stream. Streamer will map the route the stream follows. You can also trace upstream using Streamer. Imagine that you're standing along the Mississippi River in New Orleans. You're wondering not only where the river began but also which other streams drained into the Mississippi River before it made its way to your location. With Streamer you can also: locate your area of interest by specifying stream or place names; by entering latitude and longitude coordinates, enter the identification number for a U.S. Geological Survey streamflow gaging station, find out the names of streams and waterbodies by clicking on them, print maps of your downstream and upstream traces, create concise or detailed reports for your upstream and downstream traces, learn about current or historic streamflow at thousands of locations along America's streams, and find out about the places your stream trace passes through with just a few mouse clicks.

"This educational Web site, designed to serve as a resource for students, teachers, and the general public interested in the biology and identification of mammals in North America, was developed by the External Affairs and Public Programs Division of the Smithsonian Institution's National Museum of Natural History. The resources we make available are derived from the Museum's unparalleled natural history collections, its scientific research, permanent and special exhibits, libraries, and through collaborations with other organizations and individuals with special resources to complement the site.\n\nThis Web site includes detailed descriptions, images, and distribution ranges for more than 400 mammals native to the North American continent. The primary resources for the site have been based in the continental United States, but as the opportunity occurs, the site will be expanded to complete the species found in Canada and Mexico."
