Last June I parked overnight at  KMLE (Millard) southwest of Omaha.  On preflight the next morning I found bird droppings on the prop and inside the cooling intake.  I pulled the cowl and found a nest being constructed over N0. 1 cylinder.  The airplane was only stationary for about 16 hours and on an active ramp.  When I got home I constructed a pair of cowl plugs and have not had a repeat yet.

I'm reminded that birds only need a half hour of unattended time to stuff a bunch of nesting material inside the cowling.

This is the season for birds nests.  Look more carefully than I apparently did.

Lucky there was not a small fire under the cowling.
