Bell's v. Sagebrush


I was out in Borrego Springs on Saturday (gads... didn't know about the Catbird when I went... shoot!) and while I did not find the Le Conte's Thrasher I was targeting, I did find either Bell's or Sagebrush Sparrow (out on Borrego Springs Road).

I'm just not sure which it is.

Would someone be willing to take a look at my pics and see if there's any information in them that might help to resolve it? I changed it tonight on eBird from Sagebrush to Bell's/Sagebrush.

Link to the flicker set is here: 

Thanks so much for your time.
