Spent Thursday morning in upper Madera Canyon looking for the Crescent-chested Warbler and Aztec Thrush seen there the day before. Very slow birding in the canyon, only one flock and a couple loose groups of birds--Bridled Titmouse, Ruby-crowned Kinglet, Golden-crowned Kinglet, Brown Creeper, White-breasted Nuthatch, Red-breasted Nuthatch. No sign of the rarities. Fortunately, the upper canyon is a great peaceful place to spend time--rarities or no.
POSTSCRIPT: Nobody saw the rarities on Thursday, but others were able to refind the Aztec Thrush on Friday and Saturday, and the Crescent-chested Warbler showed up again on Saturday. The warbler seems to move around constantly and is real hit or miss, mostly miss.
