Brief Escape

Dear friends I have seen from the streaked kitchen window almost every noontime.

This was taken after the rain on the parkway.

There is the realization that I will be able to amend my life in this lifetime. The most problematic issue now is how do I negotiate a fixed schedule with Friday evening and Saturday off work.

"For instance: the light that Travis and Tom are shining on the front of the truck has a strong blue and ultraviolet emission, because that's the part of the spectrum across which deer see best—far better than we can. Deer vision was explained to me in some detail by a man who has studied it: Bradley Cohen, an assistant professor of wildlife biology at Tennessee Tech University. 'At dusk, when deer are most active, UV light is the most available thing,' he said. While we struggle to see detail in a purply dark dusk, a deer sees it clearly in a bright blue. Our twilight is their noon.

[...]

Here's something else unusual about deer vision. Deer see best in an elongated strip across their field of vision—a 'visual streak'—rather than in a central core of visual acuity, as we do. It would be like reading a book with your peripheral vision. Deer can't read, obviously, but the setup helps them detect a predator trying to sneak up on them.

Some birds have a visual streak, too. It's useful for hunting prey and for traveling. A migrating bird with a visual streak can study the whole horizon without moving its eyes or head (205-6)."

We have a deer herd on Stephenson with each doe with twins or triplets. We replenish the bird feeder often.

I am awake; soon to go to work, with sinus congestion mixed with pollen allergies.

I have heard the objections to suburban deer, and I still feed them. They live in the woods and water at a small creek. There have been zero vehicle collisions, but the hostas do not stand a chance. They know us, and look in the window to leave them a bite of black oil sunflower seeds.
