Goldfinches and siskins love these tiny thistle seeds. Requires a dedicated niger seed feeder.
Niger seeds come from the teasel flower heads. So beloved of goldfinches, siskins and in some locations, blue tits. You will need a dedicated niger feeder as the seeds are tiny, so will blow out of a conventional feeder. We have heard of 50+ goldfinches in one garden feeding off of these tiny seeds! Incredible. An alternative to niger seed is sunflower hearts for attracting goldfinches. Beautiful birds and in large numbers in-and-around the Nantwich area - we love them.
