Notes on [[underline]] Larus belcheri [[/underline]].

There have been a number of these birds around from time to time during the last few days, and I have been able to watch them occasionally in the intervals between watching Inca Terns.

[[margin]] [[image - one vertical line and one crosshatched line]] [[/margin]] Pairs and single birds seem to have "stations" favorite rocks where the birds can be seen most of the time. These "stations" are very far apart - nothing like a colony - but there is occasional visiting back and forth. I haven't been able to follow this at all; but some of it looks like "pairing", like the Herring Gulls in Virginia.

[[margin]] [[image - three vertical lines and one crosshatched line]] Some notes on Long Call Note + Long Call. Voice is a particularly piercing high-pitched scream. This "piercingness" is particularly noticeable in the LCN The LC is somewhat more melodious. Voice is clear like Herring Gull - not hoarse like the Ring-bill
