Interesting crow behavior!

[John Bois <jbois@umd5.umd.edu>]

At this very instant, outside my window, a crow is wallowing in the short
grass, dragging its body across the lawn so that its breast is contacting
the ground.  At first I thought it was trying to cool itself off after a
sprinkle of rain that just fell.  But this is what it is doing: there is
an ant's nest just there.  It is dragging its body over the nest so that
ants will crawl or get stuck in its feathers.  Then it stands up straight
and pecks the ants off its belly!!  Tool use, indeed.  Inventiveness.
Insectivory.  Stone the crows!
