There is a wild avocado tree on North Garfield Street in Alhambra, California. (The fruits are very small). When the fruits ripen, the ravens come for a feast. They will defend the tree, trying to drive off unwary pedestrians.
In neighboring San Marino, I've seen ravens at a four-way-stop intersection dropping the acorns from live oaks onto crosswalks, but only on the right side of the road. Here is where cars go the slowest as they come to a stop, and then pull away, breaking the acorn hulls. Cars going over acorns at higher speed shatter them, so apparently ravens like their acorn meat chunky style, not creamy.
