Endangered Species Day May 16, 2025

Endangered Species Day

Each year on the third Friday of May, people worldwide recognize Endangered Species Day—a day to celebrate, learn about, and act on behalf of at-risk wildlife. First launched in 2006 by the Endangered Species Coalition and conservationist David Robinson, this event inspires local and global efforts to protect threatened animals and their habitats.
