He's nervous because your new to him. And YES with my Quaker I had to clip his wings to get him back inside his cage cause he wouldn't stop flying off when I'm trying to put him up. He's a escape artist too even though we have most doors tied off, he still figures out a way to get out. They're wonderful birds really, but it will just take some time to get him used to you. It took me a bit to get Cracker to get used to me cause he was living with my family who adores him dearly. I handfed him and raised him myself. My family didn't used to like birds but Cracker was such a intelligent bird that my family fell in love with him. They took care of him when I moved an hour away and didn't have a stable place to put him until I found a stable home instead of a apartment, family didn't want him to go for awhile until when they were moving closer to me then they were willing to let him come home to me. I miss mine dearly as he was killed by one of the dogs we've rescued, he escaped his cage and jumped towards me when I was only 3 foot away, but the dog got to him first before I could and ran off with him. It shattered me completely. Quakers are really intelligent loving birds, you will love him dearly for sure!!!!
