Yes, and they're pretty much all gone from this coast now, RT. It used to be that you'd see a canary in just about every bay from here to SE Alaska. Once they invented the machine called the "Iron Chink" the canary business really took off. (No, I didn't make that name up and yes, it probably is racist name since I'm assuming it was meant to mean a machine that did the work of the Chinese guys who originally cleaned the salmon by hand on the gut line).
So canaries and logging were the two main industries all up the coast.
It became problematical when people, particularly the wives of the canary managers, began keeping canaries as pets. Their cheerful chirping was a pleasant sound in the rainy gray weather of the coast. But pretty soon it became confusing when you heard someone talking about a "canary." Did they mean the manager's wife's pet bird, or did they mean the big roaring, clanking, steaming, smelly thing on pilings that was turning salmon into dinners?
Eventually, after a series of remarkable accidents due to the misinterpretation of the word "canary," it was decided something had to be done. Since the canaries that were turning fish into dinners did so by stuffing the cooked fish into cans, someone thought, "Why not change the name of the canary to
cannery, after the cans they use?" The name of the bird would remain the same.
So they did, and literally overnight all the canaries up the coast became canneries.
