On some winter evenings I would see large flocks of crows in south
Columbus headed somewhere as Casey describes. I haven't seen them since
I switched routes home from work several years ago.

Also several years ago during a walk I happened upon hundreds of crows
grazing in a grassy field midday in Columbus (in the vicinity of where I
would see the flocks flying). Some of them flew up and swirled closely
over my head and sounded very annoyed trying to intimidate me while the
rest continued foraging. The next day I went for a walk in the same area
and noticed thousands of shallow holes where the crows had dug up or
looked for shallow insects. It almost looked like someone had run a soil
aerator over the area.

The West Nile Virus took its toll on crows and blue jays here in
central Ohio but I am starting to see somewhat of a comeback.
