I'm glad that you finally heard from the vet. Was the word that she used aspergillosis? I think that it's a pneumonia that birds can get.

Unfortunately tiels are notorious seed junkies. Back when there were a lot of tiel forums many an owner was frustrated by not being able to wean their tiels off of seed.

Dorian knew that he was loved and cared for. I'm sorry that things became stressful for a time but birds are very adaptable and adjust to situations. I'm sorry you lost him.
