Oh, #HellOfABird is trending? Smithsonian ornithologist Peri Bolton ( @Periperipatus) is a Dr. Who fan AND can #SpeakBird. She gives us the calls of three

species: the Sulphur-Crested Cockatoo, the Australian Magpie, and the Tawny Frogmouth. #SpeakBird? Share and tag your calls!

The Sulphur-Crested Cockatoo and the Australian Magpie are easy to spot in urban areas, but you’ll have to keep an eye and ear out for the camouflaged and nocturnal Tawny Frogmouth.

Sulphur-Crested Cockatoo (Cacatua galerita).
