The hawks usually perch in the high trees near the the troll bridge or cruise the sky above the farm on days where thermals ( upward movement of warmer air which allow effortless gliding in the sky ) are especially good. Their keen distance vision can detect even the slightest motion on the ground so any snake that strays into well mowed grassy fields or a strawberry patch usually becomes easy pickings for the hawk.
Red-tailed hawks are normally very reclusive and generally avoid people but they have adapted to our suburban farm environment and regard me, the tractor, and our customers as sort of unpaid "jungle beaters" that drive their prey out into the open. It is not uncommon to see them perched high on a electric pole above a crowd of U-Pick raspberry customers patiently waiting for their next meal to be "scared up".
