Inspired by the old poem, Sing a Song of Sixpence, pie bird vents have long since added a homely touch to pies, kitchens as well as serving the functional aspect of cooling pies. I happened upon the November 2010 issue of Country Living in the grocery store and saw these little black birds and had to find out more. You can have these adorable little crow pie vents for your Thanksgiving or Christmas dinner, just purchase them here. Sing a song of sixpence, A pocket full of rye. Four and twenty blackbirds, Baked in a pie. When the pie was opened, The birds began to sing; Wasn't that a dainty dish, To set before the king? The king was in his counting house, Counting out his money; The queen was in the parlour, Eating bread and honey. The maid was in the garden, Hanging out the clothes; When down came a blackbird And pecked off her nose. There was such a commotion, that little Jenny wren; Flew down into the garden, and put it back again.
