I thought I'd create this thread much later because the aviary will be built in 2 years but today we had a small argument how to built it 
The idea I like the most is to build the aviary and build a tunnel connecting it and a window in our house, which would direct to their inside aviary (no cages anymore).
My dad said that almost nobody leaving in a house keeps parrots inside and it's better to build a separated small building next to the aviary - I don't like this idea and I disagree that almost nobody keeps parrots inside because I know that many people do it - most of people who keep parrots only outside are breeders who have 10+ birds and I'm not surprised by it - but only 4 birds are gonna be in our aviary
My mom is worried that parrots may be too stupid to learn going through the tunnel. My question is how do you think - can they learn this way between their outside and inside aviaries? IMO they can however the beginnings could be hard - I had to catch Bourkes few times to show them the way to their cages, later they started coming back without our help/we just have to show them when it's time to return. It's more complicated with Angela, I'm not sure if she would be brave enough to go out
