Blackbird like a Grey Plover

Today, after cutting the grass, I have been able to observe the behavior of hunting of Blackbird and the behavior has remembered me enormously the Plovers.
Blackbird arrives at the grass, walks, stretches the neck, look round searching a few movement of the grass, returns to walks, watches and attacks, removing an appetizing earthworm.
Now, changing the bird and the habitat:
Grey Plover arrives at the salt marsh, walks, stretches the neck, look round searching a few movement of the mud, returns to walks, watches and attacks, removing a appetizing worm.
These behaviors can see in others thrushes, Mistle Thrush, Song Thrush, Robin....
Birds with great eyes, necessary to catch the little movement.



You can see similar behavior here:
