Building a nest

This mourning dove was hard at work building a nest. She would fly to the ground nearby the nest tree and start picking through twigs, stems etc. on the ground. She would pick something up then drop it back on the ground then she would pick something else up then drop it back to the ground. She would do this every time until she found a stem or twig that met her exacting standard then she would fly back to the tree and add it to the nest. Sometimes she would take a large twig or stick and sometimes she took a single blade of grass. Of course I have no idea why she was so picky about what to use for the nest but it was fun watching her at work and I imagine she knew what she was doing. Here she is returning to the nest with a small blade of grass. I shot this photo at White Rock lake in Dallas.
