Alan beat me to it, see Pyle Vol 1 page 85-86, though I do not get "outer"
 looks like "front"

Hi -

I was surprised by your comment that Burrowing Owls do not have feathered
tarsi, so I looked at a bunch of images - some mine and some online:
Burrowing Owl tarsi have a sparse covering of fine, somewhat hairlike
feathers.  Sometimes scales seem to show between them.  Their length and
density appear variable, which I suspect results from wear.  The tarsi on
Jason Crotty's photos appear to be within the range of "featheredness" I
found in the images I located of Burrowing Owls.

Little Owls have feathered tarsi and Burrowing’s don’t so a good view
should make that determination fairly easily.

Great.   It was tucked in late today.  While it is very likely a Burrowing
Owl, the views I had of it did not show as much white over the bill as I
expect for Burrowing Owls.  Maybe it is an age-related thing.  But just for
fun, see the links.  The white over the bill seems to be variable on Little
Owls.
