Continuing at Union Station. I arrived at 6:30PM and the owl appeared at 7:05 sitting on atop the building to the left. It stayed in that spot for just over 2 hours mostly preening and keeping watch. Just after 9PM she put on a great hunting exhibition chasing birds up and down the facade for 10-15 mins before settling back in on one of the statutes on the facade.
Visible from pavement. About 2m height in a bush.
Bird was injured. Dropped down at my feet. Sent to vet and was adopted by vet tech. Good ending.
