I am fascinated with watching the behavior of birds. I confess to standing for hours trying to capture them doing what comes naturally. Finally got a shot (not a great one) of this American Robin pulling the worms from the ground. As I watched them it looked like they were cocking their head to one side to "hear" the worms - when actually - they were scrutinizing the ground with one eye to SEE the worms.
I never knew that!!
