RE: Head-turning sound

"We make small head movements all the time and the brain is presumably equipped to make use of them."

I just tried ultra large head movements. We just got back from a walk down to the river and through the woods as it were. Since I'm married to a 'birder' I was trying to locate pecking by ear. Even cranking my head around and trotting back and forth I never really managed to get a fix on it. The problem is the Z axis, it's really hard to tell how far away the creature is especially in a stand of trees. You try to judge by the reverberation but it's iffy. The tweety birds are easier since the radiation is more direct, peckers make a lot of the tree resonate. It ended well as she finally spotted the Red-breasted sapsucker on top of a snag, but I'm sure it had flown from where it was. When I was trotting along the road trying to get a bigger base angle I was thinking of our conversation concerning head position. Guess that proves that stereo is for the birds...
