My 30 year old cockatiel is thriving on these exclusively for most of his life! My vet said it couldn't be done, and he would have to eat pellets. My pet is very happy and healthy on 8 or 9 of these a day.I've been feeding this to my bird for a very long time. Amazon's product, packaging, and service met all my expectations at the best price I found.Love this product for my cockatiels. They love it too!!Left in plastic bucket takes on chemical smell..so remove to different container..Bird loves these.My birds love the NutriberriesGood product . My parrot loves it.I have 3 cockatiels and 2 lovebirds, each kind of species are on a large cage.My cockatiels were affraid of the berries when i first put them but eventually they got curious and started eating them, my lovebirds, on the other hand, started to eat them as soon as i put them in their tray.However the design of the cage leads to wasted berries, since the birds pick them up and crumble them and the bits get lost on the bottom of the cage which the birds cant reach, i guess this will be true to many customers so at times when checking my birds i found them at the bottom part of the cage looking down at the wasted nutriberries.What they do is that the cockatiels eat them at the tray but the lovebirds pick them up and go somewhere else to eat them.What i noticed is that both kind of birds just eat the seed parts and avoid the pellet parts of the berries, but thats just my birds since i also have tried to give them veggies with no success.Ill change their cage for another kind soon so i will try these again in the future.Now I did not eat one to review the taste but my bird seems to love them. She is 22 years old and I have been feeding her these all her life. That's why she still acts so young because of the quality of these seeds. Your paying for the quality and to have my bird for this long is priceless.If my 4 cockateils could write this they would be saying more please!! I have tried pellet food before and the birds did not like it at all. This food is a hit with them.They took to this straight away, so much so they stopped wanting the seed so much. They get so excited when I open the lid, and its really good as a training treat. They have decided that this is their main food, and there isn't so much waste with this because if its dropped you can just pick it up and put back in the feeder. This size tub is good value for money with no postage to pay even better. The delivery was extremely fast. I had looked at this product before with different companies and smaller size packets and was put off because the post charge was more than the product itself so took the chance that the birds would like this and ordered this large tub, so pleased that I did.This is my second order from this company and would highly recommend.My search continues??, I have two cockatiel. One is fussy eater the other will eat any and every thing. It's a very large tub so think most of them will go over before I get to the bottom with just one bird eating 3 or 4 balls a day, I keep offering but hes not keen. I just wanted a ready made second dish of food for them. They love their fresh fruit and veg with cockatiel seed.My bird loves this. Excellent food and great product.I bought one package of this treat for my beautiful parrot, "we were both pleased" my little parrot Cherimoya loved it so very much, so I ordered another similar package..it arrived BUT in a very small envelope, hence, most of the treats were crushed, it looked more like pellets to be eaten versus round treats for Cherimoya to enjoy and play with her little TREAT balls. SHAME ON YOU FOR MAILING THIS TREAT BAG IN A SMALL ENVELOPE AND FORCING IT IN THE PACKAGE, THEREFORE AS INDICATED ABOVE...it was a mess. Treats are treats and should not arrive crushed. Shame on you amazon, shame on you whomever sent such a shabby bag of treats. Plus, it is not/not INEXPENSIVE.Great product. I was skeptical of buying food online for my bird but I was post surgery and couldn't get out to buy anything for him. This exceeded my expectations. The product itself is great, it was shipped sooner and faster than advertised and the food was not expired or anywhere near expiring. (which is supposedly an issue for some people that order pet foods online.)Would buy again in a pinch.
