This morning I hiked through a beautiful area of the Ochoco National Forest near Prineville in an unsuccessful effort to photograph a Great Gray Owl. After that I headed to HWY 380 to look for the Blue-gray Gnatcatcher where I also a struck-out.  My reward for persevering however came in the form of a brief, and I hope diagnostically adequate, look at a Lark Sparrow (Oregon Photo-Life-List number 270) and a close encounter with a couple of Ash-throated Flycatcher which appeared for all intents and purposes to be on territory on North Shore Rd.   

While going through the photos at home I realized that I also had a couple images of a sparrow, from the Owl area in the Ochoco's, that I cannot positively ID. My two top choices are (sub-adult) Chipping or Brewer's Sparrow.  

Your thoughts on the embedded images of the two sparrows will be much appreciated.  

And our Oregon-Life-Photo-List No. 270 if it holds up (Lark Sparrow):

Ash-throated Flycatcher:

We hope you enjoyed the photos - and we thank you in advance for your comments.
