This week at Bob Heirman park my students found a log with dozens of skulls
and bones on it. Since a Northern Harrier is often seen here I assume these
are regurgitated pellets from that bird. The log is in a large area of
grass. I have not seen so many in one place before. Is this common for
Harriers to have, as one 8th grader so eloquently put it, a puke perch?
