To me the bottom line is we, the humans, are the boss. We have the birds living in our homes and we must take care of them, keep them busy, feed them, train them, etc.
As for how much do you push them to do what you want them to do, think of it this way. We have all, well most of us, had good bosses and bad bosses. The bad boss is always shouting orders, telling us what to do but because we don't like their approach or personality we may not do what they want us to do. On the other hand there is the good boss who just has something about them and when they say it's time to get to work we are happy to do what we are told to do.
I try to be that good boss with my birds so they are happy to "work" for me and when they don't do what they are asked to do then I take a step back and look at what is really going on, see if there is a problem and then fix it.
That's my story and I'm sticking to it!
