[[underline]] belcheri [[/underline]]

November 16, 1955, Chincha Peru

Have had more opportunities to observe more of the same behavior.

V&HF by bird on ground toward flying mate about to land.

Was able to watch a copulation attempt in considerable detail. [[image - symbol for female]] FB in H. Sound should really be transcribed as "Klioo", just like other [[underline]] Larus [[/underline]] gulls. [[image - male symbol]] walked about [[mostly in V. Once down in M posture. (Couldn't hear call, if any). Then stood in V, giving series of LCN sounds, [[underline]] relatively soft [[/underline]], (bill opening & closing visibly) Interspersed with series of downward movements, mostly gosts, once drinking. Then mounted copulation like that of related species. Apparently a Cop Call - but couldn't hear sound - which means that it must have been [[underline]] very soft [[/underline]] - much softer than either LCN or FB note. [[image - symbol for male]]'s bill semi-closed during Cop. Call [[image - bill]] Part Cop display mutual V&HF

The various downward movements, including PAG & "drinking", seem to take the place, in this species, of the Pr. movements of other species. At least in pairing and sexual situations. 

Relatively low intensity HD's appear to be "rounded"
[[image - sketch]]
Higher intensity forms are apparently straighter.
