In 2018 in Battle Ground, WA while walking in a wooded area behind my house I viewed a very large, tall, owl in the top of the trees looking down on me. It was early evening and there was a bird nest in a tree close to the ground which had an egg in it. The mother was upset I was so close and made quite a ruckus which caused the owl to be agitated as well and finally flew off. Quite exciting for an evening walk. I believe it could have been the Great Grey Owl. I remember being impressed by it's size.
