Hissing and clicking

What do you think you hear in this recording? A clockwork? A model railroad?
Or maybe a snake?

090713, Eurasian Wryneck Jynx torquilla, juveniles, near Leipzig, Germany

Yesterday I ringed some juvenile Wrynecks Jynx torquilla. What you can hear
is their defense call. For me it was quite an impressive experience to see and listen
to and this hissing and clicking bunch of young birds in the nest-box.
Their defence behaviour is optically remarkable too. The Wrynecks fiercely turn
their heads all time to mimic a snake. Combined with the sound it didn´t miss its
effect!
