Started in 2006, Endangered Species Day is “a celebration of wildlife and wild places” intended to promote the “importance of protecting endangered species and everyday actions people can take to help protect them”. Every year on the third Friday in May — and throughout the month — zoos, aquariums, parks, botanical gardens, wildlife refuges, museums, schools, community centers, conservation groups and other organizations hold tours, speaker presentations, exhibits, children’s activities and more to commemorate the Day.
