Around the turn of the year a Barred Owl – Strix varia, was reported in Boise, Idaho. The owl has been seen regularly for the past month. Barred Owls occur in Boise once every few years as vagrants from somewhere unknown. This Barred Owl showed up in a city park on the east side of town, only about a mile from the foothills. The peculiar part is that the park is adjacent to the Boise River, a large wooded area, and acres of open field. Instead of occupying these more wild, less human areas, the owl has chosen the back yards adjacent to the park to roost. The bird hunts the park edges and greens at night, apparently having loads of success. This behavior is a testament to the hardness of this species against human disturbance. It is one of those few species that seems to do well with the world we are creating.
I took the video above a few days ago just before sunset. The owl was alert, no longer snoozing. The most interesting thing about the video is the birds behavior coupled with the anthropogenic noise. In the clip you can hear a man playing fetch with his dog, someone closing a house door, and many other human sounds typical of urban living.
Why is this Barred Owl able to tolerate a lifestyle like this, yet other species are so sensitive to disturbance? The Barred Owl’s closest North American relative, the Spotted Owl, is certainly having a hard time with the way we are changing its world. These types of questions are worth entertaining as more and more we change the world around us, better for some but certainly not for all.
