We've been on Twitter for over seven years, but we've been "tweeting" since 1916. Thanks to technology, we're able to share our long history with an ever-growing, ever-engaged real-time audience as we approach our centennial next year. Social media is also a powerful tool for sharing daily happenings and inspiring wildlife advocates like you to join us in our ambitious mission to lead the fight against extinction. Thanks for joining the conversation and being a champion for wildlife. Check out our best tweets of the year, and stay tuned for more fun, educational, inspirational tweets.
