Here's a story I wrote for the BirdNote radio show which should help explain your odd looking robin:

I saw a white backed robin! He was at Flaming Geyser Park, in the second big meadow from the turn onto the park road, not toward the flying discs area but into the park. He flew from and to the woods near the river along with regular robins. I think I've seen this guy before, but I wasn't sure I had identified him correctly. This time I got pictures! I posted them on the bottom of my web page at https://myyarncraftsplus.weebly.com/birding-gallery.html . He's at the bottom of the page. I'd appreciate opinions on if I am correct and why a robin might have a white back? Sorry, the pictures are not great quality.
