And another SLATY-BACKED GULL from Wisconsin, USA

Sometimes these gulls get TOO much analysis. Even birds that are phenotypically one species might have plenty of genes from species X, Y, or Z. Where does one draw the line?
Here's a SLATY-BACKED GULL I distantly photographed here in Wisconsin back in November. Didn't get to study it much as it was around for only 15 minutes or so.
