[[circle]] 144 [[/circle]] [[underline]] modestus [[/underline]], Nov. 27, 1955, V. The sound of the "rattle tone" LCN, without the "rattle tone", could be transcribed as "heeyar". The apparently unmated [[image - symbol for male]] I watched earlier this morning was back on his knoll temporarily. Giving LCN's toward flying birds. (Checked on these. They [[underline]] do [[/underline]] seem to be "hostile" patterns definitely directed [[underline]] toward [[/underline]] flying birds - rather than expressions of frustrated sexuality). One bird landed about 2ft away. [[image - symbol for male]] (let us call him A) did O, then V, then attacked newcomer who had just stayed in V. Perhaps A already has an attachment of some sort. He suddenly woke up from a daze. Went into M, ran to a bird about 15ft away, did V&HF, M, M&HF, M, M note, M&HF, M etc. The other bird just looked at him blankly from V. Then A flew off on a circular flight. This didn't look as if he were having too much success * comm. area field 10:45 [[circle]] 10:45 [[circle]] V.

[[underline]] V before attack - V&SS after attack [[/underline]] - pr M is very common by one or both birds of pair during short rushes at neighbors which appear to be low-intensity or "muffled" forms of redirected hostility provoked by [[mutual?]] pairing behavior Bird, apparently A, lands beside another some distance from his territory. Does a couple of LCN's before landing, changes to M notes before he lands, then does M + M note immediately upon landing, then M+HF-M-M+HF-M-M+HF-M, etc. Other bird just looks about and runs away. Even though A may be semi-territorial, i.e. defending a territory from time to time, he is also gone from his territory from time to time, and I imagine that he is usually displaying in some other part of the area during these away periods. (I know he is in some cases) The early pairing behavior I have seen so far, is remarkable for its variety Confirms a certain impression of "fluidity" in behavior already conveyed by variations in the L.C. performance. This species appears to have quite a remarkable range of innate patterns upon which it can call in situations which are apparently similar. The species appears to be more "fluid" than other gulls I have studied.
