I'm so sorry keep him company and monitor his behaviour and appetite.. he may get depressed and lose weight, try to give him lots of treats and attention. I'm not sure what else you can do for him, hopefully someone who has been in the same situation can advise you.
So sorry for your loss I would think lots of attention cuddles and treats will be the answer Oh a vet check will also be a good idea to make sure theres no risk of infection worms anything . Hugs X x Teresa
I know this won't ease your heartache but when my guinea pig lost his mate, he was only consoled when we got him another friend. Could you introduce another bird, not necessarily the same type and not in the same cage? Alternatively maybe a change of room or cage would help as well as loads of attention and treats of course.
Sorry to hear this. I wonder about my birds as well. My tiels are bonded to the point where if one gets out of sight of the other one they scream nonstop until they are reunited. If one died it would just be awful. I wish I had advice.
I'm very sorry for you loss. This is rough. While getting him a new friend may be a good idea, quarantining that new friend is way more important. You don't know what diseases that new bird could have and it could make you male sick. It's best to do a quarantine period first to make sure that neither bird has anything that can make the other sick. A check at the vet is also a good idea for both birds.
