Waddle this way for some African penguin facts: African penguins are believed to be one of the 1st penguin species to be discovered by humans. One of the African penguin's most distinctive features is a small pink gland above each eye, which helps them cope with high temperatures in South Africa. African penguins are also widely known as "jackass" penguins, for their donkey-like bray. #AfricanPenguinAwarenessDay #PengwinningContent #WaddleThisWay #SanDiegoZoo #EndangeredSpecies
