Crow Smarts

It’s been a long time since I bought a children’s book — until today. Or at least it arrived today. I heard about it on a science show, Kids book goes inside the crow’s smart bird brain, and could not resist.

Look at this:

The New Caledonian crow shapes a hooked tool to extract grubs from logs.

And this:

The damn clever thing shapes another digging tool by tapering it so that it has a thick end for holding and a pointy end for digging into crevices.

The crows here have straight beaks, not slightly curved ones, and eyes more to the front of their heads than do other species of crow. Since these traits enable a more efficient use of tools (more difficult to work them with a curved beak and harder to get the aim right with eyes further apart) it appears that tool use has favoured the evolution of these smarter crows.

If like me you want to catch up with what the kids are reading and learning, check it out….

The Australian Magpies

I loved this program when it was first broadcast a few months ago and appreciated the ABC’s Radio National “re-releasing” it as a podcast. I always love watching magpies and so often notice fascinating behaviours. For some years many times I went outside to hang the washing out the same magpie would fly down and perch on the clothes line, looking intently at me as if to greet me and spend some time with me. In Australia we easily take their beautiful song for granted so I was pulled up with some surprise when an overseas tourist expressed amazement at the sound.

Anyone interested who hasn’t yet heard the program, do listen to

The colourful life of the Australian Magpie

The opening seconds is all you need to hear their sound.

Other details that fascinated me:

  • they are listening for the sounds of grubs etc beneath the grass
  • they recognize individual human faces
  • in the event of the loss of the male partner the female soon accepts another male replacement who continues to care and provide for her chicks
  • their black and white colour is no camouflage but functions as a highly visual signal for territorial purposes
