Oh Sweet Canada
The White-throated Sparrow has a lovely, melodious song. The mournful sound has a couple of different mnemonics, or memory aids, that help birders recognize the tune. In Canada, birders sometimes say the song of the White-throated Sparrow sounds like it is singing "Oh sweet Canada, Canada, Canada." If you need help remembering the memory aid, here's a cute original design from Birdorable to help you!
