Field notes

Species entries pair common names with scientific names, and many identify the recorder and license, including Creative Commons BY credits. The homepage says the displayed set comprises the 24 species with the most recordings; its examples include frogs from several regions, such as the Spring Peeper and Common Eastern Froglet. A location prompt offers a way to narrow the list to frogs recorded in a chosen place.
