Song or call & method of delivery: Although we didn t know what we heard at first, we did hear a rough hiss while getting ready to search for the owls. Only later did I find that this is a sound could be a BOOW. One individual (photographed) was giving a skiew call and a bird farther away (20yrds?) was giving a repetitive cheep call, but much softer. Without observing the second bird, we were unable to use the owl s extreme reverse sexual dimorphism to determine which sex was making which call. (Audio)
Behavior: Observed while perched ~12 above the ground in a fir, close to the trunk.
Habitat: Thick groupings of mature firs surrounded by meadows and within 30 yards of a small body of water.
Similar species and how
were they eliminated:
Northern Saw-whet Owl- pale bill, white facial disc, and vocalizations eliminate this species.
Previous experience with
this & similar species:
Although this was my first known encounter with this species, I have spent a lot of time in the presence of all other common Utah Owl Species.

Additional comments: This was the first October I ve been free to search for Boreal Owls in proper habitat. I m usually busy hunting in habitat not conducive to finding them. I do feel that this bird is a lot more common than many are lead to believe. After this observation I reached out to others that have recently located Boreal Owls and it seems as though there have been multiple owls at multiple locations that are too far apart to be the same owls. Like I stated on the recent sight record, this bird is sparsely observed due to lack of access during breeding season, not because of rarity.
