← Great tits join mobs with neighbours they know

If I'm not mistaken, there is evidence for the release of oxytocin in response to phermone stimulation. I wonder if anybody has investigated neurobiological substrates of the long term neighboring great tits?

I would think they live and fly too far apart for any hormonal effects to be communicated, unless they are from the same nest, or gathering at a food source.

Birds and other wild animals take a great deal of notice of alarm calls from their own and other species.

Many eyes cover a much greater surveillance area.

That is why clumsy, noisy humans can walk through wild woodland and see very little, but hear the chorus of alarms. Even quiet humans will be avoided by much of the wild-life.

A walk looking at tracks in recent snow, can tell you how much you are NOT seeing!

Birds like Arctic Terns will unhesitatingly and effectively attack large animals such as humans if they approach their nests.
