I checked in on them late last night and it looked pretty miserable up there. No obvious signs of trouble, but a dead bird wasn't really anything I was looking for. It was then that it occurred to me that the late season timing of our rain and this storm was an issue because the chicks were just too big to fit under the mother and didn't have feathers yet. Interesting that it's the kind of thing that you learn on nature shows - rain, no rain, hot, cold, timing, etc. Too bad one of them didn't make it. But, that's precisely why there were two. Now the odds improve for the remaining one since it gets all the food and has a better shot at fitting under the mother in case we have more rain. It also just occurred to me to check on the pair in Azusa Canyon. We almost went up there last week but passed. In light of this we'll go up there next week for some pictures.
