What a beautiful little juvie! I find the bands hard to read in this pic, especially the numbers.
However, if the bands are indeed 69/BC, black over green, I did find that band number. The juvie would be from the Statler nest in Buffalo. There were two chicks this year, Erica and D'Arcy. At banding, one was given the bands 69/BC, and the other chick had the bands 70/BC.
Shortly after banding, D'Arcy became very ill, and she did not survive, so this juvie would be Erica. Erica was grounded at least once after fledging, and I have heard nothing of her since.
Here are a couple of pics from banding:


I'm just going to post this quote here because I also have the surviving Statler juvie from 2016 listed as Erica. I'm not sure which name is actually correct, but we can hopefully figure it out. I believe Sage had some input as well on FB since she was there at that banding. I didn't actually have a name for the one who didn't survive when I did the family tree, so I can correct that now as well as add band numbers.
