Kaytee® Ultra Wild Finch Blend is a mix of four select ingredients designed to attract more finches and is preferred 3-to-1 over Nyjer® seed alone*. Since birds identify food with their sense of sight, Kaytee® has applied this knowledge of visual attraction to create this custom blend of seeds that will attract more birds to your backyard. Kaytee® Ultra Wild Finch Blend does not contain fillers and is ideal for year-round feeding of a variety of wild birds. *Extensive national field testing has shown our Ultra Wild Finch Blend is preferred 3 out of 4 times when compared to Nyjer® and attracts more birds. Nyjer® is a registered trademark of the Wild Bird Feeding Industry.
