[Tweeters] Help identifying bird call please

[heidi narte]

Hello Tweeters Friends,

I have an odd request. This morning while out on my usual walk around 
Normandy Park I heard a bird call I've not heard before. Of course it 
stopped before I could download a recording app on my phone. It was a 
loud, raucous, "ow-ow ow-ow ooowwww." Kind of like what I emit when I 
step on a piece of gravel in bare feet. It seemed to be coming from a 
crow that was circling around, although, I'm not positive. It was 
staccato-like, akin to a jay but definitely not a Stellars or Scrub. I'm 
stumped. I haven't heard this call in the 20 years I've been walking 
around my neighborhood. Any ideas welcome! Many thanks!
