I solved the mystery of the radically decreased Lesser Goldfinch numbers at my thistle feeders this summer compared to previous years! It finally dawned on me after seeing a similar post on NEBirds that maybe the reason is cuz I have been finishing up the very OLD bag of thistle seed. That has happened to me several times over the many years of feeding it. And sure enough, after changing to all new seed in my feeders Tuesday, I now have a regular clientele of goldfinches! The seed was rancid. So, lesson learned for the ??th time! Same can be true of rancid suet; unhealthy for birds.
