Plumbeous Vireo at Solano Highlands Park, Del Mar area, 25 Sep

Nothing big deal, but I think this PLUMBEOUS VIREO was a recently arrived migrant. Found in the row of the Tipu trees adjacent to the school and basketball area at the south edge of the grassy sports field.  It took off soon after I located it about 07:50 am, at which time students and their parents started arriving, so I left.  The rest of the park that I covered was pretty devoid of any migrants except maybe a Western Wood-pewee and a single Yellow-rumped Warbler.   List at https://ebird.org/checklist/S74033929
