These blocks are really good size for my cockatoo. She especially likes the orange and yellow ones, but the blue and green ones get torn apart too. She seems to prefer the alphabet blocks over these, but if she's bored she'll pull these apart too. It's very difficult to find these wooden blocks anywhere else, and it was nice to find them here and buy them in bulk. having wooden blocks available to tear apart keeps my cockatoo out of trouble.
