On a recent hike through open grasslands with a few conifers mixed in we had a close encounter with this Northern Harrier who must of been defending a nearby nest. They were making plenty of noise and circling around above us as we walked the trail below. Occasionally they would dive bomb us flying straight overhead but never actually trying to make contact with us. We just pushed on through their territory walking a bit faster with each dive bombing pass yet pausing to watch this beautiful birds pass so close. Once we had ventured out of their space peace was had for all.
