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.
“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!”
“The Niger Seed from Vine House Farm is much enjoyed by the goldfinches in my garden. The birds queue up to go on the feeder. The quality is so good and it is very fresh. You can tell that from its glossy appearance. I find that I am buying bigger and bigger bags to keep up with demand ☺️.”
