Do any photographs exist of that quail Robert that belonged to Margaret Stanger?

Yes, they do. I have one that was sent to me by Mike O'Connor, owner of Bird Watcher's General Store in Orleans, MA. Please note that the quail Robert adopted Tommy & Mildred Kienzle as her foster parents. Margaret Stanger was a neighbor of the Kienzles and was a "quail sitter" for them. I wish I knew where the Kienzle's lived as that does not seem to have been recorded anywhere. Cheers, Jim HullyMundelein, ILEmail: xenospiza@gmail.com

p.s. I visited Orleans this past summer (2014) to find out more about Robert. I talked to many people but the highlight was spending the day with Cathy Baldwin. She illustrated the original book and still lives in Orleans. We visited the Kienzle's house (#8 Crystal Lake Drive - looks just the same as the drawing in the book), the Orleans Historical Society, Mike's store, and of course Margaret Stanger's home. The most touching part of the day was finding Robert's grave. She is still being watched over by those two stone quails....
