Hi Pajarita
I have kept birds for some time (about 20 years) and we had Sam from 2000 at about 6 months old, He had a 12foot by 8 foot outside flight but came in every afternoon into a cage that was open in the living room or on his stand but was kept overnight in a cage in the conservatory. Before he showed signs of the illness we cannot pinpoint any reasons that he was stressed. The very first visit to the vet bloods were done, the bird was scoped and swabs were taken from the Tricia. Cultures were grown and a broad spectrum antibiotic was administered. He was X-rayed and his lungs were clear When the results came back the antibiotic were were using was deemed to be the best to use. As he was sill not getting any better and he was loosing weight we went back to the vet and a camera was passed down his windpipe and the growth was much worse X-rays were again taken and both his lungs were infected, more samples from the windpipe and bloods were sent of for cultures to be grown but he deteriorated over next few days so we decided to have him put to sleep as he was fighting for breath and was exhausted.
The vet did a full ortopsy and confirmed his previous findings but said he had never seen it this aggressive and he has been an avian vet all his life practising in South Africa, Dubai and the UK. As I said earlier there was no change in Sam's behaviour to either my wife or myself he just seemed to go off his food and then all of a sudden had breathing problems. Sam was a very health bird and has only ever given us cause for concern once before and that was when we took the pond out of the conservatory and he had a discharge from his nostrils? (Don't know the correct term) and it was decided it may have been because of the change in the humidity so he had a humidifier from then on, this was about 10 years ago. His yearly veterinary MOT always came back OK.
The only stress factor that I feel we could change would be to let him sleep more because he seemed happy to be out on his stand until 2100 hours most nights but being in the conservatory (very light no blinds) in the summer dawn is early and we did not account for this so got much less than 12 hours sleep but it is winter here at the moment so this is not a factor in this case.
"if you are looking to get the same kind of relationship you had with your bird - which, would not have been typical as sick birds are much, much, much more mellow and, taking into consideration that B&Gs are the mellowest parrots to begin with while Senegals are little firecrackers," As I said earlier we had Sam from about 5 or 6 months old and he has been easy to handle except for occidentally brushing his feather sheaths (he lets you know it hurts

) and he would NOT let you cut his claws, he was not a very good washer (except in thunderstorms) he would hang on the wall of the flight getting soaking wet, I never did understand the difference between that and the shower

but would tolerate being misted if he had to.
I am looking for something similar to what we had with Sam and I do realise that a smaller bird is going to be different but the companionship and love given and accepted is what we are after, so it looks like Senegal's are not the type of bird we are looking for.
I have to say in the UK there does not seem to be the same rescue centre type set up as in the USA and the only way I can see of getting a bird this way is through the small adds in the papers or on the internet and I am a bit reluctant to do this because I think it is the opposite of what has been said on here in that you do NOT know what you are getting, I would love to go visit a couple of times and check the bird and its owner out but I don't think that will be an option over here, I think its going to be a case of "Give me the money and here is your bird" I may be wrong and may be I should investigate it a lot more before making assumptions but using a breeder that I have had a bird from before and who looks after my bird when we are on holiday is a much safer bet.
