Niger seed (nyjer seed or thistle seed) is known to be a favourite of finches, due to the shape and structure their beaks, which are suitable for a smaller type of bird seed.
“I did not order niger seed. I ordered sunflower hearts and peanuts but the order never arrived. DHL said it couldn't access the address: this has never happened before and orders have always been promptly and correctly delivered before.”
“So impressed with this company. Excellent quality, the birds are very happy. Delivery is great too. Order one day early and it is despatched either the same day or the next. The courier company keep you updated regularly!”
