Cul de canard Cul de canard Cul de canard (CDC) (French for "duck bottom") are the feathers from the back of a duck directly around the preen gland (uropygial gland); they are very buoyant due to preen oil produced by the preen gland. They are used when tying dry flies for fly fishing. They owe their buoyancy to their proximity to the ducks preen gland which secretes an oil distributed by the duck as a cleaning and waterproofing measure. It is unnecessary for the angler to add additional oil by way of floatant. Flies incorporating CDC are easy to dress requiring no floatant
Antisemitic canard place, as individuals, in so many areas of American life. I always thought that was the American dream. The Anti Defamation League documented various antisemitic canards concerning Jews and banking, including the myth that world banking is dominated by the Rothschild family, that Jews control Wall Street, and that Jews control the United States Federal Reserve. The ADL notes that the canard can be traced back to the prevalence of Jews in the money-lending profession in Europe during the Middle Ages, due to a prohibition against Christians in that profession. "The Protocols of the Elders of Zion" repeated this canard.
