"I have a large, outdoor aviary at my house that, in addition to smaller birds, has several species of conures and a pair of cockatoos (and 3 "fixed" rabbits) -- so I go through a LOT of bird food and fresh veges! This is by far the best mix for "parrots" that I have found, with a good percentage of pistachios (which are the favorite of the cockatoos). The cockatiels, parakeets and parrotlets pick at the smaller pieces, too, to supplement their diet and anything that hits the ground is gobbled up by the bunnies! There is no "filler" junk that the birds won't eat, so there is no waste factor! Excellent value for the price!"
