We only had two CA quail in our little neighborhood when we moved to Utah. My DH named them Bob and Irma. They came and ate seed twice a day. Even after a couple of years, we never saw them with babies. I had taken a Magpie with a hurt foot to a bird rehab lady, and she asked if I had any quail where I lived. I told her about Bob & Irma, and she asked if I could try to get them to adopt a bunch of parentless babies that she had. I was willing to try, so I brought them all home in a large cage, and left them in the backyard. Bob and Irma adopted them right away!
All 15 of them! When I went back to pick up the Magpie, the lady asked if I could take the second batch of babies. I figured it was worth a try again. Much to my surprise, Bob and Irma adopted all 15 of those, too! Imagine those two quail with 30 babies! What a sight! 20 years later, and the neighborhood is VERY populated with quail, and I was so glad that I could help with that. We sure did enjoy them! Our Golden Retriever also adopted the whole family, and they would walk within a few feet of him. He'd just lay there, making sure that none of the neighborhood cats got close.
I sure do miss him! He'd just lay out in the backyard, protecting those babies, and it was the sweetest thing ever. The biggest shock to me was that the quail trusted him. Never expected to see that, but they had no fear of him. My next Golden would have never done what he did. We told that story many times to new neighbors, when someone would mention how many quail there were. A neighbor even wrote a book about it 4 or 5 years ago, and gave it to us for Christmas. I'm sure he knew that we had brought all of those quail there when it happened, but he probably just forgot. He sure did enjoy hearing about it the second time. 
We have quail here, but they are a lot more wild than Bob and Irma were!
