Barred Owl
Strix varia
The barred owl is considered somewhat subdued and drab in coloration compared to the sometimes rich coloring of other sympatric owls. Overall, this owl is greyish-brown or brown. The brownish color extends from the head to the back. Barred owls are scalloped with white bars on the mantle and the back, bearing as well some whitish spotting on the wing coverts. Voice: The barred owl is a powerful vocalist, with an array of calls that are considered "spectacular, loud and emphatic". Calls probably carry well over 0.8 km (0.50 mi). Its usual call is a series of eight accented hoots ok-ok-ok-ok ok-ok-buhooh, or the "typical two-phrase hoot" with a downward pitch at the end.

Ural Owl
Strix uralensis
Like most Strix species, it has a broad, rounded head with a correspondingly round facial disc, barring a tiny V-shaped indentation. The Ural owl has, for an owl, an exceptionally long tail that bears a wedge-shaped tip. In colour, it tends to be a plain pale greyish-brown to whitish overall (with more detailed description of their variation under subspecies), with a slightly darker grey-brown to brown back and mantle with contrasting whitish markings.
