If I were you i'd go with the umbrella cockatoo. I don't know what the adoption fee is, probably expect to pay a couple hundred. But keep in mind with adoptions their probably going to be antisocial birds that were abused.
And will take a very long time to get used to you, and sometimes will never let you hold them. Their very smart birds which means they need something to keep them busy. Swapping in different toys into their cage all the time, some music, and a social life.
Otherwise they could get bored and scream or feather pick. I have a pair of birds so they keep each other company, and they have their toys so they don't cause any problems. A single bird by it self will need more attention.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
