We had 2 budgies who were very much in love with each other but only one Blue was really tame.
2 weeks ago he got a concussion, we took him to the vet, he spent some time on oxygen and in a warming chamber and then a few more days at home being kept extra warm and quiet. He seemed all better.
This afternoon my son noticed that Blue was breathing funny again so he picked him up and cradled him in his hands. Blue was breathing really quickly and then he flapped his wings a couple of times and fell over. He took a few more breaths and then just went still.
I suspect that Blue suffered a stroke or an aneurysm related to his head injury a couple of weeks ago but I guess we will never know.
My son Luke is heartbroken and I am worried about Aqua since they were so strongly bonded and Aqua doesn't seek out human companionship.
