Gambel's White-crowned Sparrow. This identification is made by the fact that the bird has a pale lore. A bird with a black lore would be from the eastern subspecies.
One of the field marks distinguishing this as a Northern Shrike is that the black stripe only contains about half of the eye. If this was a Loggerhead, almost the entire eye would be contained.
Two more field marks identifying this as a Northern and not Loggerhead Shrike: The bill is long and sharply hooked, the Loggerhead's would be shorter and not as sharply hooked; and the breast is faintly barred. An adult Loggerhead would not have bars on the breast.
