When I got Jazz my sennie, it was a 3.5hr car drive home... she seemed fine in it, although she was moaning quite a bit.
She spent a week at home, then on the following Saturday she went on a trip to see some friends in London, which is 45mins train, 5min bus and another 15 mins train (all overground
).
She was surprisingly content in her rucksack (a Pak-O-Bird Travel Carrier Small). She was quiet for most of the journey, just on the way back that she chirped a bit.
I have also taken her to my sister (who has an African grey). That is just a 20 minute walk.
I have not yet (and I am not sure if I will) taken her overnight somewhere.
I think it is a good thing to get them used to going out and see new things, I cant wait for the weather to improve here in England so she can start going out and staying outside rather than just travel.
