Where was it coming from and what was it?
It stopped a few seconds, then started again.
At last I saw what it was. A couple of birds were pecking at the remains of bugs stuck to the grille of the Rolling Steel Tent.
Hang around a while, my avian friends, and you can have some eggs, too.
The birds didn't want their pictures on the Web, so they flew away. The former bugs didn't complain.
