First of all congrats on your new family member! 

Good on you for giving him a good home though!
It should be large enough for a few types of perches (e.g. 1 natural like a tree branch, 1 rope and 1 cement), food and water bowls, a few toys and the bird.


Did the pet shop only clip one wing? If so do you know someone who can do the other? It's unbalancing and potentially dangerous for a bird to have just one wing clipped, like trying to row with only one paddle. Ergo will be lots happier evened out. If you are comfortable doing it yourself you can carefully wrap Ergo in a towel and use a pair of nail clippers to clip one feather at a time. I find it hard to go wrong with this method. Having two people helps a lot.


I told myself exactly the same thing and guess where i got Cookie.
It's a shame pet shops don't separate them when things like this happen.
What size is the cage (measurements)? I saw a "cockatiel" cage at the pet shop the other day which was too small for even a budgie. Pet shop people will often tell you anything, but judging from your initial dislike of cages in general i can't imagine you coming home with anything too small!
Moving is really stressful for birds, so yes it's normal for them to be quiet and afraid when they get home. I wouldn't be too worried just yet, cover up part of the cage to give Ergo some extra security and give him a few days to settle in. Runny poos for the first 24-48 hours can also occur from stress, but if they persist it could mean illness in which case a vet visit would be necessary. I expect he will perk up in the next couple of days though!
Seeing as he's not a baby i would go about taming him the slow way with lots of patience. Let him be apart from changing his food and water for the first few days and whenever you pass his cage talk quietly to him and tell him how gorgeous he is and anything else. This will get him used to you and your voice. Then start spending more time near his cage talking to him, etc and eventually start putting your hand in his cage and seeing if he will step on your finger. It will probably take a while, but it will be worth it for you and Ergo.
Cockatiels aren't terribly loud in general. The males sing but not constantly. He probably won't make a lot of noise until he's settled in and comfortable in his environment.

Your boyfriend is right that he probably won't eat for the first little while. I would only leave him with seed and water until he's comfortable and then introduce the veggies. I would stay away from crackers and other salty/fatty/sugary foods altogether. If you can buy some spray millet a lot of birds find that irresistable and it might get him eating.
Looking forward to seeing Ergo!!
