A compassionate soul at our congregation put up this barrier to protect a nesting killdeer.
The black and white speckled eggs are camouflaged quite well amongst the rocks, but car tires are no respecter of birds' eggs.
Every time I tried to sneak up on the nest, the mother would quickly scamper away and begin her "wounded wing" act to lure me away from the nest. I wanted to try to get a shot of her nesting, but my little digital camera doesn't have a sufficient telephoto lens. Still, I managed to zoom in enough to get this shot through the chain link fence surrounding our playground.
