When I was a kid I lived in Steveston for awhile. At that time it was a real fishing town with three operating packing houses. About half of my friends were Japanese kids of fishing families. One of their older brothers used to make his own Sake. He would take what was left of the rice mash and put it on fence posts for the gulls and watch them get pissed.
The Japanese, fishermen nor sea gulls are corvids....
