Just thought I'd pass on this observation: the bluebirds have yet not flown south for the winter due to the hot weather in Southern California. However, there appear to be fewer sparrows and pigeons around these days, perhaps simply because of the unseasonably warm weather. Yesterday it must have been 79 or 80, and the day before it was probably around 84. Unlike in New England, there are not only no leaves to turn, but the leaves wouldn't turn if they could. That said, at around the 5532' elevation level or so, there are indeed deciduous trees that can turn. You can see those by heading 25.3 or so miles up Highway 2. Best of luck!
