Took me 3 tries to figure out why the chickadees stopped coming to my feeder
I spent like 4 weeks last spring wondering why my usual morning crowd of chickadees just vanished. First I thought it was the seed, so I bought a fresh bag from a different store, nothing changed. Then I moved the feeder to a different tree branch, still no birds. Finally I realized the sunflower hearts had gotten damp and clumped up at the bottom of the tube feeder, they were probably tasting mold. Has anyone else dealt with birds avoiding a feeder for no obvious reason?
