[[pink marking]]
I noticed this afternoon that [[male symbol]]'s tended to sing in response to any squeaking or "whooshing" noises I made.  This occurred even when the [[male symbol]]'s had been quite silent for some time before I began to make noises.  The [[male symbol]]'s usually sang with considerable vigor in response to my noises.  Surprisingly enough, however, even when they sang most vigorously, they made no attempts to actually approach me!

In any case, this singing reaction of the [[male symbol]]'s is still another indication that hte song of this species is hostile.

One [[male symbol]], probably responding to my sounds, repeatedly sang song phrases, each one of which was introduced by a short but quite unmistakable R.

One brief fight between two neighboring [[male symbol]]'s was accompanied by hurried emphatic songs & R's, in alternation.

It is obvious that the R of this species is either more aggressive or (perhaps more probably ?) higher intensity than the song.

This is a very common type of singing posture of the small black species.  [[image: drawing of bird]]  Notice the head shape.  This sort of "semi-erected" shape is quite common, although by no means always present.  The amount of fluffing of the breast and belly is quite variable, but never very extreme.
