40-year old mystery-- found on San Francisco Bay shore in 1979

Greetings, Forum! I hope someone out there might be able to shed some light on a 40-year old mystery.
In 1979, as a 9-year old boy, I found this piece on the edge of the San Francisco Bay at a yacht club in Sausalito, California. For over 40 years I've had the piece, and all my attempts to find out more about it have been fruitless. I am guessing it was not an antique of any kind when I found it, because I'm guessing the surf and turf of the shoreline would have broken it to pieces. But who knows... maybe *you* know? One thing I can say--it appears to be a little pitcher inspired by a bird, with the spout the bird's beak!

Thanks for your time and consideration!

I would look towards Ecuador and Peru

It’s signed on the base so likely to have been made in the latter half of the 20C, so 1960s is very possible. Looks like a low fired raku
