So sure enough, I was blasting down that same road a couple of days ago, and there, big as life, was the Snowy Owl. In roughly the same tree as where I saw it a few months ago, give or take a tree or two. I slowed down to take a look at it, and it swooped down across the field to the west. As I've noted before elsewhere, raptors don't take kindly to being inspected. It kinda disappeared in the glare of the lowering sun, so I drove a ways further and turned down a side road where I could look back to where I had been.
It appeared to be right on the crest of the little hillock of pasture, tending to something on the grass...probably a morsel of prey it had swooped down on. I watched for a few minutes, but it was too far away to see much other than a small white shape engaged in bird business. So I backtracked down the road a ways, then turned around with a better idea of where to look.
By the time I got parked on the shoulder, the owl was perched high in a bare skeletal tree twenty or thirty feet above the ground. It looked at me for a moment, probably annoyed for the disturbance and attention, then turned to the west and flew away. That's almost four months this bird--not a native to our area--has been in residence. That's quite a treat for us.
