The Cornell Lab’s BirdSleuth K-12 education program will be hosting a webinar for educators focusing on Global Big Day. The webinar will be offered four times, twice each in English and Spanish, on 9 May and 11 May. See below for times. The English version (1 hour) will give educators the confidence to work with students around migration, eBird, and Global Big Day. During this webinar educators will learn how to define migration and understand the purpose of these seasonal movements; understand the concept of citizen science and the program eBird; explore citizen-science data through an educators perspective; and how to participate in Global Big Day. The Spanish webinar (30 minutes) will be more generalized and discuss how educators can engage their communities in Global Big Day.
