Oh, #HellOfABird is trending? Smithsonian ornithologist Peri Bolton ( @Periperipatus) is a Dr. Who fan AND can #SpeakBird. She gives us the calls of three https://abs.twimg.com/emoji/v2/... draggable="false" alt="🇦🇺" title="Flag of Australia" aria-label="Emoji: Flag of Australia">species: the Sulphur-Crested Cockatoo, the Australian Magpie, and the Tawny Frogmouth. #SpeakBird? Share and tag your calls!
