The last few times I have walked down the street to the dumpster I have noticed a couple of birds who get quite alarmed and animated when I approach. Today Grant and I went for a walk and took the garbage out and I noticed the birds again so I went back in and got my camera.
According to Audubon Arkansas the bird is called a Killdeer.
This is what they are protecting. They lay their eggs in gravel and they blend in really well. This shot is close enough that you can see them pretty well.
This is the bird's broken wing act. Apparently they try to lead prey away from the nest by acting like they have a broken wing and when they get far enough away they fly to safety.
