One of the things I really like about Corvallis is that so many different trees flourish here; there are at least two different kinds of walnut within a block of our house. We’ve harvested some already for eating, but there is a slightly menacing corollary of that bounty manifesting itself about this time of year. As if the hazards of being hit by a falling walnut or having your feet roll out from underneath you on a carpet of them wasn’t bad enough, when shedding fruit in great quantities, these trees draw crows in flocks large enough to qualify as Hitchcockian.
In attempting to devour the crop, crows can be seen trying to crack walnuts by attempting to pin them between their feet to peck at, or drop them from lamp posts, or wedge them in the manhole cover, or (my personal favorite) hurl them at human interlopers. Displaying an amazing variety of tactics, and using elements of the natural environment to their advantage, as well as (superficially, at least) learning from past mistakes presents something very close to empiricism.
