In processing my photos I came across this photo of what I had assumed was, at the time I photographed it on November 11, 2025, a Golden-crowned sparrow.  As I processed the photo I realized that the bird had prominent yellow eye lores, a diagnostic for a White-throated sparrow which I had in the yard a week or so ago.  

I then did some research (Sibley and the internet).  I couldn’t find any photos of a Golden-crowned sparrow having yellow eye lores nor could I find any photos of White-throated sparrows having a golden crown.  Then I added “hybridization” to the internet inquiry and found that there were known instances of hybridization between the two species!  From what I found, the bird I photographed has some of the most distinct head markings of any of the hybrid photos I could find.  

So barring any alternate theories or information from more experienced/knowledgable birders, I’m referring to this as a GCSP/WTSP hybrid!  (I have two more photos of the bird but this photo clearly makes the point!)
