You can provide 2 kinds of seeds in the same feeder using the Perky-Pet Large Dual Mesh Seed Feeder.

The Perky-Pet Large Dual Mesh Seed Feeder features 2 independent seed compartments that allow you to serve thistle seeds and sunflower seeds at the same time – or you can opt to provide the 2 seed choices you prefer. It's like having 2 feeders in one, and the large cobalt blue metal feeder provides superior durability and functional design. The top overhang helps to shield seeds from wet weather, and the mesh design provides ventilation as well as perches for clinging birds. A circular bottom tray has drainage holes and the rim provides more perching areas for a variety of seed-eating birds.
