Customer Feedback: This is Bronte, a beautiful red tailed black cockatoo. She is thoroughly enjoying a foraging block stuffed with nuts (both block and nuts purchased from a wonderful site www.parrotrescuecentre.com. She loves this toy as she is a big chewer and the block allows her to slowly reach nuts I have squished into the block, without cracking them open too easily. It keeps her entertained for long periods of time, which is rare for this curious and cheeky girl! Highly recommend these blocks for anyone with birds that are big chewers!
