pine siskins

I have an average of 2 pine siskins dying each month near the bird feeders. This has been happening since April. They will just sit on the ground or on a branch and then the next day be all fluffed out and then dead by the next morning. No other species is dying. They are eating black oil sunflower seeds and thisle seed.

The only disease among birds that I am aware of is the eye disease in house finches. I am not aware that pine siskins are contracting it, too, though they might be. Just to be safe, I would wash all your feeders, and purchase new seed from a different source, just in case the problem is with the seed you are feeding.
