African #penguins are believed to be one of the 1st penguin species to be discovered by humans. They’re also one of the most endangered as their numbers have declined by 60% in the last 15 years. Our dapper residents are just the beginning of a large flock we hope to have over the next few years. ❤️🐧 #penguinawarenessday #birds #sandiegozoo #EndExtinction #photo by Marcia Siggins Jonas
