This is one of the most dramatic broken-wing displays I have seen exhibited by a Killdeer.I have also posted this video in a HD 720p format on my Video Blog. I was riding my bike in an industrial area on the outskirts of Boise when a family of Killdeer, including a few chicks ran out in the road. There was grass nearby and I tried to herd them that towards it to prevent the chicks from getting run over by trucks and cars passing by. I had my HDV camcorder available so I captured a little hand held footage of one of the adults displaying the "broken-wing" behavior when I was close by. The chicks were eventually led to the grass where they were quite well hidden and safer until they ran out into the road again.Birdwatching.com has a good description of Killdeer behavior and the ability of the chicks to start running as soon as their feathers dry after hatching.
