Virginia,

One important distinction is the location from which the call arises. I have
radically different hearing ability in my two ears, so when it's important
that I localize a call, I need to ask for help. The point here being that if
the call you're hearing arises from the woods, that is likely then an owl;
the snipe's winnowing always arises from the sky. However, if you're facing
a hill, the source of the sound may not be clear if it's coming from within
the trees or above them. Your comment about the call not moving is
important, and suggests more owl than snipe.

I find that the owl's call is a series of distinct notes whereas the snipe's
winnowing is, to use a musical expression, slurred.

Snipe are a lot more common than Boreal Owls; however, I think the owls are
more widespread than we're currently aware.

Note that Boreal Owls should only be calling from forests with a boreal
flavour to them. According to the recently-bound and polished thesis by
NatureNS subscriber Kathleen MacAulay, which I just happen to have on my
desk in front of me :) ... birch-fir mixtures are the type of forest in
which all BOOW nests have been found in NS. So, if your woods are entirely
deciduous for example, the likelihood of the bird being a BOOW is lower.
