Holmes R. 1959 Erolia fasciata 20 June Barrow, Alaska Pls see above. Also when I approached Close, he would raise the one wing [usually the one near the intruder]. 21 June Barrow, Alaska A pair seen again on the beach ridge. Aerial displays were noted several times, and the P was seen to chase two Sanderlings and a Baird's Sandpiper. The ground display was given once when the female was present. The female was approached out time as she was feeding and when I was within 10 feet of her, she cropt off using the "mouse-run" behavior. This behavior is where the bird appears to crouch and runs in this position, as if it was running away undetected. The feathers on the back are ruffled and the head is out straight in front of the bird. This is often the type 1 behavior a bird uses to leave at roost or when it is going to a nest. The territorial boundaries were carefully guarded again and were patrolled in the same low-flying manner. The second bird was not seen
