Nyjer does not last forever and where I purchased mine they told me that after the same experience you had, that it does lose its ‘appeasability’ if it is not kept cool (they told me to keep it in the refrigerator) because the oil in the seed dissipates over time and warmth speeds that up..
I purchased a new fresh bag and instead of throwing out the older seed I mixed about 10-15% of the old in with the new and got my goldfinches back along with eating all the seed (new and the older seeds).
That worked for me.

  Good Morning – 
Wondering if anyone is a bird seed expert that can help me with a question I have regarding Nyjer seed?  I have a bag of Nyjer seed that is approx. 1 year old that I just put out but have not been getting much activity from the gold finches.  Initially I had it located under an Aspen tree by a multi-seed feeder.  After not much activity, I relocated it across the yard next to a large columnar pine with no increased activity.  Is it the seed?  I have only seen a few gold finches this year compared to years past so maybe that’s the issue.  Any thoughts?
Thanks!

Seeds with a high oil content like your thistle & black-oil sunflower seeds can, as Charles noted, go rancid. But a year should be OK. I suspect the seed that I purchase now is from last year’s crops, as new crops are just now being planted. I would guess, it’s more migration patterns. I’m having a huge number of both Am Goldfinches & Pine Siskins hitting the thistle feeder to the point that I’m filling the tube which has 8 slots for feeding, everyday. And, that’s unusual for my side of the state & location. I don’t feed any mixed birdseed, too much Millet which attracts House Sparrows.

I fill a hanging platform feeder with black-oil sunflower seeds, the tube with thistles & now, an Oriole feeder. I filled the jam cups with grape jam & placed two “Little Sweetie” orange halves on the pegs yesterday & a male Bullock’s Oriole has been hitting it all morning. Hope this helps.

Niger (aka thistle) seed does get funky after a while, the oils within seem
to go rancid (this can probably happen to any bird seed). But it can also
take a while for finches to find it unless they are already coming to say a
nearby sunflower feeder. You’ll get mostly goldfinches at the thistle
feeder in Boise (and they’ll also readily take sun flower seeds). I would
recommend sun flower only in the other feeder over a multi-seed feeder,
throw the mix on the ground if you are ok with that.

Hit the birding at first light this AM. After last evening’s torrential downpour (2 inches in 1-1/2 hr) thought the thunderstorms may have caused some migrants to sit tight overnight. Found all the usual summer residents, plus a male W Tanager, in fresh spring plumage that landed on the top of my Oriole feeder & allowed for a satisfying, long observation. Now, after warming up with a cup of coffee, headed back out to see if any Lazuli Buntings are around.
