A couple of hours of scouring No Thoroughfare Canyon this morning turned up quite a few Black-throated Sparrows, an ironic twist on the absence of the Black-chinned family previously reported. I assume we were searching the correct area, but they simply weren't there this morning. (We were on the No Thoroughfare trail, where it crosses a deep arroyo, up and down the arroyo both ways, up the trail another 1/2 mile, and up and over the little plateau to the left (south) of the trail).
Upon seeing yet another of many Black-chinned Hummingbirds buzz by, I mentioned off-handedly to Deb that there was a Black-chinned over there a minute ago... "What?!" Oh... not the sparrow... Sorry....
The good news was that we found the previously reported Gray Vireo, which was a new one for us. Also of interest in the canyon today:
