[[underlined]] modestus [[/underlined]], Nov. 27, 1955, VII.

Might stress one pattern included in an earlier count of [[male symbol]] behavior [[male symbol]] did O, parallel but with partner, [[underlined]] then pointed bill toward partner at end of O [[/underlined]] - just where I would expect HF

Note about orientation of the LC performance toward partner. Two main types, face to face, and side by side facing in the same direction, with all sorts of intermediates. HF, of course, only occurs when birds are more or less side by side; but I think that T after O and L can occur with any sort of orientation.

About the orientation of other hostile + sexual displays - I think that their orientation is perfectly "conventional", ie like the corresponding patterns of most other gulls, unless noted otherwise above.

In spite of any earlier impression, at first glance, that the condition of the U in this species (ie. "unsplit") might be "primitive", i.e. [[very?]] little ritualized; I now believe that it must be thoroughly + highly ritualized. Otherwise one would expect a great many more of the Agg variety.

ALC, as might be be expected, is usually given in the air, but occasionally on the ground Can confirm what I said earlier about the actual syllables themselves sounding like large Larus - this is certainly the usual condition Occasionally they sound a little more like Hydrocoloeus; but never so much as the ALC syllables of [[underlined]] belcheri [[/underlined]].

There have been several major Silent Pauses already this afternoon. One, a very long & repeated one, was apparently set off by 2 [[Whimbird?]] flying past very fast.

[[image - male symbol]] making repeated M notes during copulation. Bill opened slightly with each note. (This is good supporting evidence for my classification of calls. The M in this species is a muffled low-intensity rhythm sound, the low intensity form of both "Ch Call" & "Cop Call", which are muffled high intensity rhythm sounds
