Store your Nyjer® (thistle) in a cool place

Nyjer® (pronounced NYE-jer) is a trademarked name for a little black seed used by the wild bird feeding industry that is favored by the finches. It is also known as "thistle" by backyard birdwatchers because the seed looks so similar to the “noxious weedsCanada thistle and Bull thistle. A noxious weed is a plant that has been designated by an agricultural authority as injurious to agricultural or horticultural crops, natural habitats or ecosystems, or humans or livestock.

Nyjer® does not grow weeds. It is heat treated for sterilization. However it does leave a lot of shell waste below the feeder. Nyjer has a thin shell that the finches efficiently pinch between their bill, extract the seed and drop the inedible part below. At an active feeder, all those shells accumulate quickly into a little black pile.

Nyjer's high oil content makes it an excellent energy source for active birds, and it's best used in our specially designed finch feeders.

It is important to keep the food fresh because finches can be picky eaters. Nyjer has a thin shell and is vulnerable to spoilage while in the tube. Once seed starts to get moldy or becomes stale, finches will look for fresher forage. Replace Nyjer in feeders every three to four weeks if it is not being eaten actively. Store your Nyjer cool dry spot for a longer shelf life, and buy in quantities that will be used up in a few weeks.
