[[underline]] scoresbii [[/underline]], Dec. 29, 1955, II.

low-intensity. A single harsh note, or, rarely, 2 such notes. By flying adults or adults on ground (in Alert or relaxed posture, I think). Very harsh & hoarse. Sometimes note can be transcribed as "Kek"; but sometimes "Hahk".

Well! Have just heard adult, nuptial plumage, on ground, give "Kek kek kek" Al.C. Just like Belcher's Gull Al.C.

[[underline]] The commonest hostile pattern here is T! By juvs and also by adults in all plumages [[/underline]]. Quite well-marked. More extreme than most of the hostile T's I have seen in the Patagonian B.h.G's here; but less extreme than the most marked T's of Franklin's Gull. [[image - sketch of bird with beak pointed upwards]]. perhaps the most extreme I have seen so far
Accompanied by T note, apparently the same in both adults and juvs, a soft, almost whistled, "Kleeoo". Bill opened very slightly and very briefly during the note. The most interesting thing about this T, however, was its unmistakable hostile nature. (in all cases - no trace of FB), [[underline]] and the frequency with which it was given by the attacker after attack [[/underline]], (in about half the cases seen - perhaps 75-100).

No carpi-raising with T.

Some of these T's may have been silent. At least the call was very soft and the bill apparently closed throughout.

Have heard trisyllabic AlC by flying bird.

Now we get to the LCN - L.C. business; which is rather complicated.

Aerial LCN is usually hoarse and harsh. "Haah" to hoarse "Keow". Often given by bird flying near me. Then usually single notes or several notes with some pause between them. Have heard a large number of notes given by flying bird chased by a Kelp Gull (food robbing and these followed one another in rapid succession, with almost no pauses between notes. Given from usual posture or lack of posture.
