Fw: The Mouse

["Greg" <>]

I would suggest that the wren's behaviour is a 'distraction display'.  It is 
unlikely to be imitating a mouse but is behaving in an unusual manner to 
distract a predator from its young just as a Red-capped Plover feins a wing 
injury or a Pied Oystercatcher lays on the sand flapping its wings. Your 
squeak may resemble an alarm call and this would initiate the behaviour.  I 
have had fairy-wrens behave in this manner when one or more of the group is 
being removed from a mist net for banding.
