In this episode, the Histories of the Unexpected duo, James and Sam, take to the skies to swoop upon the expected history of BIRDS! Which is all about the Battle of Waterloo and plumed helmets, costume feathers, hats, the American Ornithologists Union and cruelty to birds; it’s also all about canary resuscitators, John Scott Haldane and the use of canaries down mines and in the trenches during the First World War. Who knew!
