The last time I was down on Amherst, as we were heading back to the ferry and just east of town, we saw 3 short-eared owls cross the road in front of us, I pulled over and watched the 3 turn into 12. They seemed to come out of no-where and they put on an amazing show about 40 feet off the road in the field right in front of us. I found their flight patterns to be similar to the northern harrier, hovering and diving but a little more erratic.
