I spent a bit of time with a great gray owl last week. It was later in the evening and it seemed to be looking for a last snack before dark.
I watched it crisscross a meadow of tall grass and make several dives out of sight. It came up without a catch on those.
Apparently, it felt like a change of location was required. Crossing the road she landed on a couple of old fenceposts and stared hard into the adjacent little fields but didn’t find a target worth chasing.
Success came when she flew out of a tall tree she had spent a few minutes surveying from. When she launched, it was a drop to just above the grass and then a sudden drop.
She swallowed while low in the grass and then rose out and flew towards me before alighting on a post right beside me. A couple of minutes later she went across another field and out of sight.
