I think I need to be a bird feeder tester for companies that want to put out new bird feeders!! I think the majority of the American Gold Finch are at my house? :) These little beauties have eaten 50 LBS of Black Oil Sunflower seeds in a week! think I need a 2nd job? We have at least a 100 or so of these finches stuffin their beaks? Plus all the other Sparrows, Stellars Jay and other finches.
