Snow, Stimulus, and Response
We don't often get lake-effect snow way down in southeastern Ohio, but we surely are getting it now. We've got six inches on the ground here at the farm and another few inches on the way. After being home for the holiday break since the week before Christmas, our kids are looking at a week of snow days. (The hills are echoing with the cheers of children and the groans of parents). It's a light, dry snow—very powdery—so no danger thus far of a power outage.
Fortunately we're well provisioned inside and are keeping the bird feeders well-stocked outside, too. We have about 35 dark-eyed juncos in the yard most days—more when the snow cover is deep.
This chap (photo at top), fluffed up against the 17ºF cold, was staring me down through the kitchen window, trying his best to let me know that the suet dough dish out front needed a refill.
The birds have us really well-trained. Here's what they do:
They flutter down to the feeder.
Look into it, find nothing.
Then glance in the window with a forlorn look on your face at the clueless humans.
Fly off a short distance when the humans come scrambling out the door, hands full of seed, suet, peanuts, filling the air with apologies.
Like Pavlov's dogs, we respond every time to the birds' stimulus.
