Cookiebaker, PLEASE go and get Rilla a friend. If she seems this lonely and won't sing or anything, she may be VERY upset. Did she witness Azure's death? If she did, you never know how heart-broken she is. Birds are VERY sensitive animals and if they lose a member of their flock, it can have an effect on their health. Also, PLEASE take RIlla to the vet to be examined in case Azure was ill. She did live in the same cage as him so its best to get her checked. Poor Rilla baby. I would also advise to get a cockatiel instead of a parakeet, because a parakeet that has never been around cockatiels may be afraid because of Rilla's size. Rilla may also be more happy to have a friend of her own species but of course that's a decision for you to make. Rilla was used to a parakeet so I think she'll be happy with one, but it might terrify a parakeet that has never met a cockatiel. I have a friend who has a parakeet, and I once took my birds to her house to visit her bird. As soon as my birds saw the parakeet, they went in his cage to greet him, but as for him..........he screamed and flew out of the cage, and didn't return until we left! Whatever you get, please get her a friend. Its not good for her health to stay lonely like this after having years of companionship by Azure. In the meantime, try to give her the most attention as possible. Talk to her, let her out of the cage, buy her new toys, buy her treats that she loves, and get her a feathered friend as soon as possible. If possible, tell Malone to keep her company (under supervision of course) when she's in her cage. Getting another bird will NEVER be replacing Azure. Getting a new bird will be something to help heal Rilla's heart and make her her jolly self again. Getting a new bird is the least self-fish thing you can do because despite your grief from the loss of Azure, you are getting a new baby for the wish of Rilla baby. Keep her company in the meantime and let her know that her human flock members are still with her. Popcorn and Muffin send her cockatiel hugs.
