Encouraging nonprofessionals to participate in ecological research through citizen science programs is a recent innovation and an effective strategy for gathering ecological information across broad geographical areas. In this paper, we demonstrate how reporting field-based observations through eBird, a citizen-based birding and data-recording program, can be used as a lab activity in an undergraduate ecology class. This exercise exposes students to worldwide data collecting networks in which non-scientific communities serve as major stakeholders. This lab activity also introduces basic field techniques in ornithology and allows students to answer inquiry-based research questions using a citizen science database. (Contains 1 figure.)
