This is perhaps the most common semi-alert posture assumed by the visitor when flitting about, and the one from which many CN's were given.

This posture is probably not ritualized as such.

The last note of many MCN's is rather "quavering" [[image - wavy line]].

This disputing is going on and on and on this morning.

The really highest intensity disputes, when the birds are facing one another, absolutely frozen, with occasional attacks, and extreme Gfluff and G, seem to be absolutely silent.
