by uttering clear (often plaintive and/or whistle-like) notes.

I have seen no form of WS and/or SS among the wild birds.

The Blue Honeycreepers around here still associate in flocks quite frequently. Especially in the afternoons. Such flocks may be maintained almost steadily, in the afternoons, for at least a couple of hours. They usually include approximately 4 to 8 birds. The flocks often appear to include more ♂'s than ♀'s; but this appearance is quite possible deceptive, as ♀'s are often difficult to see.

While they are in these flocks, the ♂'s tend to be very active, flitting here, there, and everywhere. They sometimes appear to prefer to flit about a  ♀, but this appearance may be deceptive (see below). They may be flitting about one another. All this flitting is very irregular. Obviously not ritualized in form itself.

This flitting is usually accompanied by a lot of low to moderate intensity hostility.

Sometimes all or most of the ♂'s tend to perform a lot of St's. These St's are often quite extreme. Usually or always with CR. Sometimes but not very frequently with a very slight trace of BL or BF (breast-lowering and belly-fluffing) I have not seen any Q or even wing-drooping or wing-spreading with the St's in these flocks. Nor have I heard any Wh Notes in such flocks. All or most of the St patterns of ♂ Blue Honeycreepers in these flocks must be silent (see below).

The ♂'s tend to make a lot of irregular up-and-down and/or side-to-side movements whenever they are in these flocks. Such movements seem to be most vigorous and frequent, on the average, when the ♂'s are performing St's; but I have not seen anything like "real," stereotyped Bowing or Pivoting this year.

Some of the ♂'s St's seem to be directed to one another. Other
