Could this be some kind of owl?
(Lakewood, CO USA)
I live on the front range of Colorado near Denver. I came downstairs at 5 a.m. today (May 31)and found this roundish brown and white mottled bird sitting on my porch rail. The brown & white almost look like a checkerboard pattern they were so clearly delineated. I had to take the pix from inside the house and it isn't as clear as it should be. He sat there until 8:30 when my husband went onto the porch.
This bird took up about 8 inches of the porch rail including his tail feathers. Tail feathers were pure dark brown. He was about 4-5 inches tall, but he sat scrunched up so I'm sure he is taller when standing. His eyes are deep, dark brown and his beak almost disappears into his breast feathers when he sits. He opened one eye, but never both. He had a pretty good wing span for a small bird. He's very round...sorry I don't know bird description words. An owl of some kind? Was he migrating through or could he live in the tall trees in the gulch located less than a 1/4 mile away?
