Ecological notes: We usually get these gusty Fall storms later on in the season, typically in November. Most of the debris on the ground is likely a result of all the leaves still on the trees, which catch the wind and want to be carried away. By November the leaves have fallen and the wind has a much less dramatic effect on the trees.

Other notes: Callan and I drove back from Fairfax last Tuesday night. Before we left we heard spring peepers (Pseudacris crucifer, formerly Hyla crucifera) calling. The roads were filled with frogs crossing back and forth. When I got home I was greeted by a chorus of gray treefrogs (Hyla versicolor). The wet weather has brought the young amphibians out in droves. At the fall equinox, the ratio of light to dark during a day is the same as it is during the spring equinox (March 21), which is roughly the time that amphibians first start singing. One theory is that the fall chorus of frogs is from confused young males that are cuing in to daylength.
