HISSING AND CLICKING
July 14th, 2009 geschrieben von PatrickWhat do you think you hear in this recording?
A clockwork? A model railroad? Or maybe a snake?
Yesterday we ringed some juvenile Wrynecks Jynx torquilla.
What you can hear is their defense call.
For us it was a really impressive experience to hear and see
this bunch of hissing and clicking young birds in the nest-box.
This defence behaviour is optical remarkable too.
The Wrynecks turn their heads all the time to impersonate a snake.
Combined with the sound it didn´t miss its effect :-)
