One good reason for providing nyjer seed is that squirrels and larger birds like Grackles do not have any interest in this type of seed. This seed type does not
sprout as it has been sterilized before entering the U.S. For the most part, this seed is imported from India. Often mistakenly called thistle seed.
Although a tiny seed it still has a shell and these shells will pile up on the ground below the feeders. Care should be taken to keep the area clean as it
can attract rodents. Most all seeds need to be cleaned up for this reason.
Sometimes it seems the chickadees and Finches just seem to not be able to get enough of this seed and other times they don't seem to go near it. I can't explain
the reason for this behavior assuming the seed is fresh and the feeders are clean. Maybe the birds are like us and just choose to eat something different.
It is important to not let the nyjer seed go bad and get moldy. This can cause harm to the birds. Heat and moisture can cause it to go bad. If it does get moldy
throw it away in the trash and wash the feeders well. Refill with fresh seed.
Thank you for taking a look and for caring about our birds.
