both birds of a presumed pair during a dispute with a neighbor on the mud flats where a whole group of birds was resting.

The "Ka ka ka ka ..." call is certainly also given by flying birds; but I don't know with what movements and postures, if any.

I have seen many terns Swooping at Skuas or on ground. These Swoops are always extreme, [[underlined]] very [[/underlined]] steep & long. It is interesting to note that they are all followed by long, steep, [[underlined]]flying[[/underlined]] Soars.

Have occasionally watched a large group of birds feeding on mud flat near the outlet of small stream. The only thing that impressed me here was the frequency of M notes in obviously hostile circumstances. Quite often given by birds not near their mates, (I am not even sure that their mates were present in the crowd) All this very reminiscent of the Herring gull. And I am sure I was right in tracing a connection between the M notes and the HD notes

Have heard 2 more L.C. performances: Unfortunately without seeing the accompanying postures; but they were obviously HD-O-T (with T note) - T (with T note), and HD-O-T (with T note) The most interesting thing about this last performance was the fact that the O part continued at least 6, [[underlined]] probably 7 [[/underlined]], syllables

The usual performance, here, of a bird on the ground toward another bird of the same species flying - low - overhead is a T with T note.

Have seen a V & HF not after attack. By an adult in full nuptial plumage when an adult in winter plumage or a juv. approached too closely
