Hello All
A key point is that the Lucy's was singing frequently around noon today.
I was there yesterday around 10AM, and on several occasions, from the correct spot, thought I heard a Lucy's Warbler. Since I couldn't find the bird, I thought I was just hallucinating, but probably not
In any case, if the bird is being vocal, that would certainly be the best way to locate it
Best Wishes
