Meteorological fall vs. astronomical fall


Meteorological fall started on September first, but the astronomical fall begins next week on September 22. The birds and animals know when fall is starting, and don't have to have a calendar to tell them.
Temperatures in the mountains generally being to moderate around the first of September, and summer lessen its grip. Temperatures during the day may reach 80, but the nights cool into the upper 50s. Next week, the first cold snap of the season is forecast.
Birds have molted, and have all new feathers now. They are congregating in large groups in staging areas, getting ready to make their annual fall migrations. Hawks ride the thermals daily heading south. Mother Nature is a bit moody this time of the year, and furnishes the mountaintop residents with splendid views of the Valley. Bill Altorp, nature photographer, caught one of Mother Nature's change of season moods.
