Hello Steve and Tweeters,
When I suggested to Steve that his sound recording was of a Pika, I misspelled the name of this animal as Pica.
My degrees are in Environmental sciences, Public health, nutrition and Clinical psychology.
Pica Is a Diagnostic entity in the Feeding and Eating disorders chapter of the DSM-5 (Diagnostic and Statistical Manual of Mental Disorders).
The first of four diagnostic criteria for Pica is:
"A. Persistent eating of nonnutritive, nonfood substances over a period of at least one month."
I have filmed Pika, but do not know if they consume nonnutritive, nonfood substances.
However, we all know the birds do consume nonfood substances-Grit, (Small, loose particles of gravel or sand)-(As opposed to True Grit, which is associated with John Wayne).
So why are birds not diagnosed with Pica?
"Criteria B: The eating of nonnutritive, nonfood substances is inappropriate to the development level of the individual
Criteria C: The eating behavior is not part of a cultural supported or socially normative practice."
So, Birds cannot meet the DSM-5 diagnostic criteria for Pica because The book is designed to provide diagnostic criteria for humans only and not other animals and the consumption of grit is appropriate and normative for birds.
And to clarify, Pika are not and can't have, Pica.
Just for fun,
Dan Reiff

Thanks all-- fascinating how it sounded like it was coming from up in a Doug fir, but weird sounds can be deceptive. I encourage all to check out the Lance Benner webinar I previously mentioned for other strange owl-like calls in the woods.

Were you near any talus slopes and at a higher elevation when you recorded the sounds?

Sounds a lot like a Pica.

I highly recommend this recent webinar by Lance Benner about strange owl calls, sounds that may sound like owls (e.g. chipmunks, solitaires, quail, etc), and other owl vocal habits.

It was sponsored by LA Birders and is focused on southern Calif mountains, but most of the species occur up here.

On a related note, I'm still seeking feedback on a strange call I recorded on a summer morning east of Snoqualmie Pass nearly three years ago. It's at https://www.xeno-canto.org/490943. Even Lance didn't know what it was.
