[[image-number 121 in circle]]

[[underline]] modestus [[/underline]]

November 25, 1955
[[Antofagasta?]] Bay.

Inside of mouth quite bright red now. Conspicuous during both L.C.'s and single LCN's.

Watching several cases of [[medium?]] late & sexual behavior.

One case of [[image-symbol for female]] approaching a [[image-symbol for male]]. She landed some distance away from him; had to approach him on foot. In V, most of the time; the usual "aux" type V. Did repeated L.C.'s to other birds as she went by. [[underline]] Notice that O was bent over backward each time [[/underline]], & this was certainly not due to the fact that opponents were above & behind her. Then approached [[image-symbol for male]] in "silent M posture",

He stood in V. Then mutual O (without much subsequent L)-V-HF-V-HF-V-HF. A bit of V parading. That is birds walked around, the [[image-symbol for male]] more than the [[image-symbol for female]], in usual "aux" type V, with much HF-ing, occasional pr. & [[gost?]] movements. ([[underline]] not conspicuous - very little ritualized if at all [[/underline]]) Occasional O performances. Quite a bit of running around in "silent M". Then finally stood in V a moment, relaxed.

(I am not sure, during the above incident, exactly how many, if any, of the O's were followed by L, and/or immediately followed by a "Long Call" T. 

Also watched copulation. Pre-cop performance was essentially like that of other gulls; but had its own peculiarities. Mutual T, [[image-symbol for male]] mostly from V, [[image-symbol for female]] mostly from H or semi-H; but both birds did some T from both postures. Much walking around one another. The T's themselves were done when the birds were very close together. [[image-symbol for female]] occasionally seemed to be trying to get under [[image-symbol for male]]; (I have seen this in other species, such as Franklin's). Occasionally [[image-symbol for female]] into silent M, [[image-symbol for male]]also, sometimes accompanied by T also. Sometimes necks almost crossed then.
