Question to any crow experts out there. I recently spotted these two standing together, and noticed that they seemed never to blink at the same time – as if consciously taking it in turns. It’s easy to tell when a crow blinks by the opaque whiteness of the inner eyelid. This went on for a minute or two.
So, is this some kind of coordinated look-out tactic crows and/or other birds follow to maximise safety? They were long leisurely blinks, so that might make sense. Or was this a one off behaviour – and I’m making up my own stories?
The things that preoccupy one on these warm summer evenings…..
Update September 2010
I found this pic going through my archives; taken in Windsor, UK. Look at the eyes. Still a small sample of two.
