After entering the park and driving a mile to the parking lot, I made the short walk up to the main (but small!) picnic area. On the way I spotted more California and Spotted Towhees and Lesser Goldfinches.
On this visit I didn't walk up to the pretty little cemetery, where (mainly Welsh) miners and their families are buried.
Instead, I stayed in the picnic area, which was busy with resident birds, including a House Wren and a couple of Western Bluebirds.
I sat down at a table to have a midday snack and was immediately joined by a very friendly White-breasted Nuthatch.
In the half-hour I sat or stood near the fountain, it was visited by a whole succession of birds: White-breasted Nuthatch, Lesser Goldfinches, House Finches, Dark-eyed Juncoes, Oak Titmice and even an Anna's Hummingbird.
Although Black Diamond isn't known as a birding hotspot and doesn't attract many unusual species, I hope you can see why I like it so much!
On my way out, I stopped near the entrance kiosk to look for Phainopepla. I didn't see any but I did add two more species to my year list: Violet-green Swallow and Bullock's Oriole.
