I had the opportunity to photograph a few Brewer's in Arizona in September
2012. I say Brewer's because they are expected there - vastly outnumbering
Clay-colored. But matching up some of the pictures to field guides was more
difficult than you would think, especially with few actual photographs to
compare to.  I have a few of my pictures available online still, if anyone
wants to compare. In one of them, the tail appears especially long. Also of
note is that the crown streaking looks finer to me than on the Queens bird.
Of course, age and time of year have to be taken into account.

 

The address is http://stevewalternature.com/steve/sparrows.htm . The
pictures to look at are labeled Las Cienagas 07, 08, and 09.

Subject: [nysbirds-l] Queens spizella sparrow

 

 I've done a bit of research on this and I think identification to species
is inconclusive, as there seem to be characteristics that favor  both
Clay-colored and Brewer's. There is more confusion because I think the side
of the face that shows a black semi-circle might be feather bases caused by
the wind or ruffled feathers, since neither species shows this. Like almost
everyone else I don't have extensive experience with either species,
especially Brewer's, but here's what I've found from checking the Nat Geo,
Sibley, Stokes photo guide, and Rising & Beadle's sparrow guide. 
 
There seems to be weak streaking on the gray nape, which I think should be
stronger for Brewer's, but shouldn't be there for Clay-colored. The eye-ring
seems a bit weak for Brewer's as well - could it be worn? The black streaks
on the back are listed as good for Brewer's by Rising, etc, but Sibley
paints Clay-colors with a similar pattern. Deborah Allen mentioned the tail
looking short for Brewer's, and most books show Brewer's with a long tail.
The overall color looks more like the grayish-brown of Brewer's. The face
pattern doesn't look strong enough for Clay-color, but doesn't really match
Brewer's either. 
 
The Stokes guide has a photo on page 666, bottom left, which comes pretty
close to the Queens bird, but not quite. There is supposed to be a
difference in the cheek color, but the previously mentioned black semicircle
obscures this, although I think it's more gray (Brewer's) than buff
(Clay-color). I don't know what to make of the faint blurry streaks on the
side of the breast, but it does match the same Stokes photo. The pink bill
is black on top, also good for Brewer's.
 
So to my eyes a real head-scratcher. Hybrid seems the easy way out, but I
don't know much about worn or transitional plumages for either. 
In any event a very interesting bird, even if it's a dull LBJ.
