Here is your little grassbird, Geoffrey. Photographed in the "channel" beside
Bittern Hide. I watched it as it went about its business quite unperturbed for
>5minutes. Even in this shot, it was not flying away, but just from one patch
to another still within view. I would just like the screen and the birds to be
a little closer. Birds have ears as well as eyes, and there is not much point
in disguising the vision of humans as long as they go on talking. Having said
that, I dropped something in Cygnus one day and swore audibly, and the Latham's
snipe resting directly in front of the hide did not flinch.
Regarding the unmotionlessness of humans as they enter and leave the hide.
That is a relatively small time interval compared with the rest of the time
spent observing.
Margaret.

Peter - I entirely agree. Unfortunately an obstacle to rectification are
those who insist that 'it makes no difference to the birds'. Hours of
controlled observation would be required to verify this. If that is right, why
don't managements everywhere build hides without rear walls? A quick test is
'the Little Grassbird Test'. However this has the disadvantage of requiring a
Little Grassbird. I would agree that a completely motionless observer in a
corner would 'make no difference' in 95% of instances. However it is difficult
to achieve motionlessness while (a) you are entering or leaving a hide or (b)
someone else is.
