While most of the birds oncentrate on eating the seed or suet that we put out in our yards, the American Robins prefer to find their own food. And they are very good at doing so!
I was watching one of them yesterday and I was amazed by how successful it was at finding worms and bugs in our lawn.
It would walk slowly across the grass.
Every so often it would stop, presumably when it heard movement on or under the ground. It would cock its head to one side to listen for the exact location of its prey.
Then it would pounce and drag out the hapless worm or bug and eat it.
As far as I could tell, the Robin caught something every time that it tried. That's a much high rate of success than most predators, many of which only catch heir prey once out of every ten attempts.
