inca                                           November 8, 1955
                                                 Obigo, (near                                                the Ballesta Is.)

Larosterna Inca Silent panics.   Then, as birds presumably calm down a little, still flying in tight flock, a hoarse "rusty", "twittering sound "Ka,ha ha ha...." form of Glik?

       Also a longer note, same hoarse quality. Might be transcribed as "Waah".  LCN?

      Ballestas Islands
       On ground. Vast variety of postures & movements.

1. Chattering. A high phase & a bow. frequently repeated
[[sketches of 3 birds demonstrating following explanation]]
Seems to be largely directed toward companions

high phase varies from something like a stretch to something like an upright

[[sketch large well defined head]]

Bow phase is very rapid, instantaneous, much shorter than high phase. Bird at bottom of bow looks rather like Goethe Settings. 

Accompanied by the rapid, chattering call, mentioned above, given in air. I think that call continues during Bow, but it is so rapid difficult to tell.
