Global Big Day
May 13, 2023
Join bird enthusiasts worldwide on Saturday, May 13, in celebrating the birds that share our lives. Two events mark these yearly celebrations held on the 2nd Saturday of May. Global Bird Day is an online event organized by the Cornell Lab of Ornithology. By participating in Global Big Day, you can be a member of the world’s largest birding team. Last year people from 201 countries submitted checklists of the birds they identified on this day. Between midnight and midnight on May 13, you can travel to a favorite bird viewing spot or participate from your own backyard. Spend as little as ten minutes or the whole day keeping track of bird numbers.
Documentations including where, when and how you identified birds, and the species and numbers of each you observed are entered on ebird.org, a platform used by millions of birders across the globe. Here citizen generated data becomes an invaluable tool used by scientists in understanding how birds are reacting to changes in the environment.
