The Chill Alarm

The first chilly weather of late summer or early autumn certainly catches the attention of humans and wildlife alike.  After months of hot weather, it is a welcome reprieve for both but it is of more significance to our wild neighbors.

Though animal behavior is most closely tied to the daylight cycle, the cool weather is an instinctive alarm that the harsh months of winter lie ahead and that harvesting is now especially important.  That may mean putting on a layer of fat for hibernation, fueling up for migration or storing food in dens or natural cavities for the lean months.  In response to this seasonal alarm, wildlife species become more active and conspicuous, delighting many humans who are also invigorated by the chill.

Last night, our low temperature dropped into the mid forties (F), kicking on the furnace for the first time since April; the first prolonged run of chilly weather is expected to arrive by this weekend.  This morning, I toured the farm, taking in the cool fresh air and watching our resident birds and mammals as they began their initial preparations for winter.
