观察细节
This appears to be an aggressive song caused by the presence of a second individual. The first vocalization matches the pi-teer vocaliztion from Nathan Pieplow's Peterson Field Guide To Bird Sounds Of Eastern North America and the 2nd, lower note is found in Song-Like Displays in Sayornis Species (Smith 1970) in figure 2d, listed as part of the song after an encounter with an intruder.
