There were some major sunspots in late October/early November last year. Sunspot clusters 484 and 486 were roughly that size. The spot latitude in your picture roughly corresponds to the size and location of sunspot cluster 486 on or around October 27, 2003 which also corresponds to around the time of the California wildfires. So it could be a bird or it could be sunspot 486.
Sunspots 484 and 486 were enormous and visible to the naked eye and were responsible for 3 of the largest solar flares on record. On November 4, 2003, sunspot 486 unleashed the most powerful solar flare ever witnessed (officially rated an X28 but it saturated the SOHO satellite's detectors so this is an estimate).
