Starlings roost

It is that time of the year again. Bird nesting.
Starlings have been a problem in the Mackenzie  Basin for years.
This year is no different.
Here we have the Aerospatiale AS350 BA Ecureuil ZK-HDQ2 (1932) parked at the Pukaki Airport with all of its external orifices bunged up with rags and other devices. (note the object in the fuselage side, below the red tarp).

It doesn't stop them trying though.
