International Flamingo Day is observed worldwide every April 26 to celebrate and appreciate the remarkable flamingo species. Launched in 2020 by the Flamingo Specialist Group and coordinated by the Wildfowl and Wetlands Trust, the day commemorates the birthday of ornithologist John James Audubon, who created a notable illustration of the American flamingo. The holiday aims to showcase the differences among the six flamingo species, which include both New World and Old World varieties, and highlights the importance of flamingo conservation and habitat preservation. Activities may include reading books or watching documentaries about flamingos, visiting local zoo exhibits, donating to conservation organizations, and sharing information on social media using the hashtag #InternationalFlamingoDay. The IUCN lists several flamingo species as near threatened or vulnerable, emphasizing the need for awareness and action regarding their conservation.
