Two versions given here, both while perched. The first was more similar to the flight song, while the second seemed to be the more common song, given while perched.
观察细节
Remarkably my second Cassin's Sparrow in southern Nevada this spring. While conducting a point count survey, I clearly heard this bird singing. Tracked it down after my survey seems found at least one individual continually singing from a perch or, more frequently, while performing an aerial display. Horrendous photos, but great audio of flight song and perched song. Very recognizable cadence.
