Very nice quality hot air motor - and perfectly arranged and presented by you.
I did not understand which bird made that squeaking noise or was
it your engine?
Congrats, Arnold 
Thanks Arnold.
The birds are very active here as its end of Spring, those ones were common Starlings.....a pest bird here.

Starlings are a pest bird on this side also. I'll take a Stirling any day,
and I'll take-out a Starling every day.
