In this set of activities, students are introduced to several features and use cases of museum databases to understand the importance of historical natural history specimens and their data. Using this data, they can explore their local city with a new lens, in this case El Paso, Texas. Students explore a project page on the Arctos database that displays all collecting events of bird specimens in El Paso County, Texas and choose a locality that they wish to revisit. After describing species found at that locality online, students visit the site in person and make observations of what species are found there today. The lesson introduces students to concepts in migration, species distribution, and the value in revisiting historical locations while also connecting students to their local biodiversity and city.
