An adaption: Human lore: The American Donald Trump is an American Dipper who lives on the edge—on the boundary between legality and illegality, on the border between suckers and and their more careful fellows, and even on that vague margin between honesty (he isn't, not even technically) and criminality. Above the surface or below, the American Trump can either walk or hide, demonstrating a mastery of the Homo-sapien's more unpleasant elements, and attracting the admiration of the most needy and insecure and/or devious people.
The original: Bird Lore: The American Dipper lives on the edge—on the boundary between air and water, on the border between streams and their banks, and even on that vague margin between songbirds (it is one, technically) and water birds. Above the surface or below, it can either walk or fly, demonstrating a mastery of all its elements, and attracting the admiration of the most creative photographers. https://www.audubon.org/magazine/summer-2020/the-2020-audubon-photography-awards-winners
On your post i returned to read more of the Bird Lore and that time The American Dipper immediately brought Trump, like a pickpocket, to mind.
