This fine textured seed, rich in oil, is often regarded as a highly beneficial food for garden birds and is thought to have played a significant role in increasing population numbers of Goldfinch and other declining species in recent years.   The seed is particularly fine - too fine for a standard seed feeder - and should be fed from one of our specialist Nyjer feeders designed with smaller gauge feeding ports than standard seed feeders to minimise the amount of food that is lost from the feeder. To further reduce waste, we recommend using a feeder tray with our Nyjer feeders to catch any falling seed.
