Could very well be black/blue looking at the at photo. If so, there are 3 Sierras that fit the bill - a 2016 female from Platte MO, another 2016 female from Vernon, WI and a 2015 from Kewaunee, WI. All locations are close enough to be possible origins for this female and 2-3 years old is the right age to start nesting. I'm assuming they have a band number for her since they have a name, hopefully at some point they will identify her point of origin.
All the others on record (at the moment) are from 1989 to 2008 with black/red and black/green bands.
Thanks for checking out on Orozco Alison - always nice to hear how Radisson grand-kids are doing!
