It does give a screech that sounds like the sharpening of a saw on an 
old stone grinder (whet stone)  but very rarely.  Many other owls give a 
similar screech begging.  At times we hear something like it during the 
winter when we disturb the owl during owl counts.

The "barks" in the first one usually means an owl that is disturbed and 
complaining about it.  Have never heard one go on so long - usually just 
a bark or two. 

There is a clip from my class CD at

ftp://owlnut.rr.ualberta.ca/pub/barb/sounds/SawWhetPygmy.mp3

It has very normal vocalizations of both owls (both owls were identified 
by visuals) and a small strange vocalization of a Pygmy at the end where 
he is trying to mimic a Boreal Owl.  I had the owl in the binos when he 
was doing this

I have never heard a pygmy owl sound even remotely like the second clip 
you put up
