Was out for our afternoon walk up Corral Canyon Dr. when I noticed a couple of Cassin's Kingbirds in a tree overhead. On second glance, they turned out to be Western Kingbirds and were immediately joined by about 10 more. First Western Kingbirds I recall seeing in the neighborhood, although the open hillsides above our housing development are good WEKI habitat. This group was almost certainly Just Passing Through. Not a particularly exotic sighting, but I'll take what I can get these days.
