I don't know if Semipalmated Sandpipers have been observed doing this. The threat behaviour I'm most familiar with for them is that of short chases.

Since this is the time of year when Blue Jays start to perform their social displays, you've probably witnessed a dominance display taking place along these lines. I've had up to 35 Blue Jays in my apple tree for the last two weeks, bopping their heads and calling, perhaps males trying to convince females to ignore the mountains of snow in this area and begin mating and nest building. I don't think the females are falling for it...

Both birds stopped fighting and placed their heads, opposite each other, flat on the surface of my deck where the dispute was taking place. They repeated this action a few times holding the position for a few seconds each time. One bird then flew off and the remaining bird did the action one more time before leaving. Has anyone ever seen this behaviour? What was the meaning of this odd behaviour? All the best. Fritz McEvoy Sunrise Valley CB ________________________________ Snap and Share.
