This oil-rich seed is a favorite for many small birds, including siskins, goldfinches and gouldians. Quail and larger finches will often feed on the ground beneath niger feeders, effectively cleaning up spilled seed. While niger is more expensive than larger seeds, it is a good economic value because little is wasted.
Many breeders are convinced that Niger is an excellent preventative for egg binding. Give a pinch of the seed 3 or 4 times per week, in the lead-up to breeding.
