feet above the ground) in very thick shrubbery. Not exposed to public view.

Both bursts of "dawn song" were the same. "Keeyah kew keeyah kew keeyah kew keeyah kew keeyah kew keeyah kew keeyah kew kew keeyah kew ......" Indeterminate in length Essentially a regular alternation of "Kew" and "Keeyah" Notes. "Kews" sometimes repeated twice without intervening "Keeyah". I think that the "Kews" were sometimes or usually higher pitched than the "Keeyah"s. Comme ça: "Kew keeyah kew keeyah ....."

The Yellow-throat uttering the second burst of "dawn song" this morning did not sit still throughout the performance. Sometimes sat on a perch for a few seconds, but would then hop from perch to perch for awhile, before settling down again temporarily. (It is possible that this bird was disturbed by my presence. From the sound alone, I think the bird uttering the first burst of "dawn song" sat still throughout)

The most peculiar feature of the performance of the bird uttering the second burst of "dawn song" was "wing-raising" ("WR")

Posture of bird uttering "dawn song" as it hopped through bushes.
