[[underline]] maculipennis [[/underline]], Dec. 25, 1955, V.

Have seen Choking - but unfortunately by bird standing almost belly deep in water. Usual form & movements. But tail not as high as in B.h.g. or Andean. (possibly due to water) [[image - sketch of bird]] Couldn't hear sound, but bill was very slightly open, and the bird may well have been uttering very soft, rhythmic repeated, muffled notes.

Have heard a few trisyllabic AlC's. But they are still relatively rare (This is certainly another point of resemblance to Andean Gull)

May possibly have heard a 4 syllabled Al.C.

The "Attack Call" might be transcribed as "Kakakakak". Very rapid. Obviously a "fragmented" LCN. (Note resemblance to Belcheri's Gull!) This leads to a certain amount of confusion; as it is very difficult, perhaps impossible to distinguish between the Attack Call and a 4 syllabled Al.C.

Am again surprised by the [[underline]] obviously [[/underline]] hostile nature of the FB note from H or with HB from semi-V. Even used by birds running to attack.

Have seen several F's, and even more H's, or semi F'-semi H's, in hostile circumstances, with R (definite, but not too extreme).

The L.C. of this species is certainly somewhat peculiar. Relatively few notes. I have seen many apparently extreme O->F performances with no more than S notes. One or two long-drawn, [[underline]] very buzzy [[/underline]] notes, with moderately open bill, in O; followed by about three shorter notes, [[underline]] buzzy but also very plaintive [[/underline]] notes in F. (The transition between the 2 postures is relatively rapid - and is usually covered by the latter part of the only, or second, O note). Bill barely opened during these plaintive F notes [[underline]] Tail widely spread during these F's. [[/underline]] (Another point of resemblance to the Andean Gull).

These plaintive F notes are very different from the notes uttered during briefer, lower-intensity F's (F's by themselves alone, or associated with brief O's) The latter are higher-pitched, shriller, not plaintive. Bill
