Friday was a tougher day to see the Couch's Kingbird, than Thursday. It was harder to find and when found didn't stay around as much.
When I was watching it, the most reliable location was 11th and 4th Streets again. I did find a berry tree just south of 11th Street, which could be seen from West 4th and Perry, where American Robins and the Couch's Kingbird were eating berries. I suspect the bird is eating and then taking advantage of the sun on 11th Street to digest them.
