Is there a difference between thistle seed and nyjer seed?
Furthermore, what kind of birds eat thistle seed?
Those that particularly enjoy thistle are goldfinches, Cassin's finches, house and purple finches, pine siskins and redpolls. Finches are squatty, colorful birds with short, stout beaks and a wide range of hues.
Similarly, you may ask, does thistle seed get old?
This is a big mistake. Old seed left at the bottom of the feeder will gather moisture, turn moldy and eventually infect the fresh seed. I've had customers bring in their thistle feeder because the birds have stopped coming. They fail to notice the grossness of the seed inside.
Nyjer seed lasts longer than other food for two reasons: Only finches, chickadees, and doves will be eating your nyjer seed. Most other birds will leave it alone. 2. Nyjer seed is so small that it takes a while for finches to eat it all.
