tk, Cardinals will not be interested in your Thistle birdfeed. Thistle will draw American Goldfinches, Pine Siskins and possible Common Redpolls, but if your wild bird seed contains Sunflower seed, Cardinals will be interested in that. Spread some wild bird seed on the ground under the feeder, this will also draw Dark-eyed Juncos, Doves and Sparrows of all types. :-D
Lots of snow my way but there is a patch I can clear and toss some there. Thank you!
