Holmes R 1962 7 june Barrow, Alaska a few inches to the side. After moving about 6 feet - the bird stepped into the cup & stood there for a moment - started picking grass from nearby & tossing it over his right "shoulder". This was done several times - the bird stood up, stepped out of the cup - & walked away - not stopping - then moved about a foot away - before feeding. The bird stood several inches from the depresssion; continuing to pick at the grass & throw it in the direction I threw up (i.e. the grass was not held until the bird had turned all the way so that the piece of grass went off to the side). Then a display flew in the direction - the bird near me flew up - gave an aerial display - chased the other bird away. The cup located opposite The Mire set / antennae / The musk site (NE 1/4th) - was 2 1/2" x 1 1/2" - bare in the bottom - with only a few roots & dark soil. No living was present at the edge - perhaps the throwing action was more a courtship ritual than a male / male protest.
