It's never too dumb to ask. yes, we have ravens. I've even seen
them in Seattle on very rare occasions.

Being no expert, I 'll let someone mnemonics or whatever.

However, there is no doubt that one of the most wonderful sounds
invented is the raven croaking and laughing in the PacNW forest
on a foggy winter day.
