I feed chicken grains to the house sparrows, great tits (I'm not sure who is responsible for naming them like that in English, but we're talking lovely black/yellow/blue birds here) and blue tits (not a word!). Spreading the love. And it wasn't leftover chicken at least.
I forgot the popcorn today, but have been givin' that gold finch seed to 'em for a while, and put some in the wild bird food as well ... now we have new and different finches eating at our feeder.
