In the last several days, I've seen sparrows in my yard that look much 
like normal White-throated Sparrows, but with throats that are not 
white, or off-white, but quite gray.  I didn't think much about it until 
this afternoon, when I saw one that was clearly a mature male - bright 
white and black head, bright yellow lores, warm brown streaked back and 
wings - and again a very gray throat.  But what was most distinctive was 
the breast and belly.  While normal adult males have a gray breast and a 
rather white belly, this bird had a distinctly white-spotted gray 
breast, and the white-spotted gray extended well into the front of the 
belly.  Couldn't see the rear belly and vent.

I'm sure I've never seen this plumage (it was quite striking), and 
neither Sibley nor NG5 show it.

Has anybody else seen this?  Is it a transitional plumage?

Also, FOY House Wren singing in my yard today.
