The reason for this is it is raised overseas. Most of the 70 million pounds of it that is imported into the United States is raised in India and Ethiopia. The cost of shipping the seed that far jacks up the price. On top of that, the United States Department of Agriculture requires that all nyger seed undergo costly heat sterilization. This is done in attempt to keep potential invasive weeds that might contaminate the nyger seeds from entering the United States. As a result, we can pay $60 or more for a 20-pound sack of nyger seed. This is definitely not a seed you want to waste.
Good information, Terry.
I live in Ben Hill county and rarely, if ever, see a goldfinch anymore. I did spot a male in early spring but they never linger anymore. So consequently, I never purchase nyger seed anymore.
I do offer meal worms and many species love this item. But it is another costly item that we enjoy when it brings in adult bluebirds along with their offspring. I believe this item is exclusively produced in China. I wish that there was a source in the USA that could lower the purchase price.
I also have goldfinches in my yard every day this time of year feeding on my anise hyssop, wild bergamot (bee balm), and Black-eyed Susans.
