Lots of folks looking for the Yellow-green Vireo this morning and I was there with many until 10 AM. Looks like I did not stay long enough and missed the Vireo, but the Black-throated Blue Warbler was also a stunner. Many of us also saw a Chipping Sparrow and Pacific-slope Flycatcher near the Guatemalan Fir. Thanks, Ken for cluing us in to that tree.
As an aside, I also missed the Dusky Warbler in Corte Madera because I did not stay there 3-1/2 or 4 hours. That's birding.
