Blackpoll and Black-and-White Warblers at Griffen Park, La Mesa
I spent mid-morning Saturday October 17, 2020 watching the ditch at Harry Griffen Park in La Mesa and was joined by a few other birders. The continuing Blackpoll Warbler made several appearances and a female/young male Black-and-White Warbler (possibly the same bird reported in early October?) was seen briefly. Lots of other warblers, but no sightings of the Lucy's Warbler while I was there.
