The upper path led me to the north and ran along the razor-wired boundary wall. In a small patch of forest a feeding party passed through consisting of Black-throated Grey warbler, Bushtit and more Rufous-capped Warblers. There was still the occasional jogger or walker, but I was getting enough time between passers-by to enjoy the quiet. Six Flags, beyond the wall, was ominously quiet and I must assume that it was shut (either for the day or forevermore).
The coarse scold of the Bewick’s Wren was audible through much of the forest and they responded quickly to pishing.
I turned back towards the entrance which was easy enough to find just by heading downhill. A few more species were seen along the way with a Slate-throated Redstart putting in an appearance at last. This stunningly beautiful flower above was found on the descent in the pine forest and I think that this is a Mexican Gray Squirrel (Sciurus aureogaster) with his bright rufous markings above and below. There are also black individuals in the park.
