Brad Anderson located this shrike in the Sawyer area in December and saw it again more recently on about his 8th pass back through the area since then. It took me 6 tries (what else are you going to do in February?), but I found it eventually. I was prepared to give it 10 tries since shrikes on their (large) winter territories are iffy propositions. Ironically Ginger found one a mile from her parents' house too (the 2nd pic is also the Sawyer bird).
I found this Mourning Dove freshly dead at Tiscornia, my guess is a casualty to a Cooper's Hawk given it looked like it crashed down out of the air.
From the underside, the outer tail feather is about the inverse of a Collared Dove's. I thought the smooth gradation from the white outer tail tips through gray, ultimately to the black inner tail feather was interesting. I was surprised when I turned the bird over and spread the tail:
