I don't know. Today was kinda crazy. I'm wondering why I saw a young female cardinal today and I know she was young because of her size. She was gobbling down the mix I bought yesterday like she really needed it. She even let me watch her from the window. Where is my camera when I need it?I've always thought January is a strange and very unpredictable month to do it but maybe it's because people feed more in the winter so more birds are visiting.
