    Equipment Note

First segment: In this recording, the juvenile vocalizes nearly throughout (a high trill). Upon the adult turning its head towards the juvenile, the volume of the vocalizations increase. The adult can also be heard intermittently. Its vocalization is lower in tone. At approx. 3:17, the adult puts its head inside the juvenile's mouth in order to feed it. At appox. 6:13 the adult flies away.

Second segment: This recording is of the juvenile from the previous recording. It is being stimulated with dead vegetation in order to encourage it to produce the call.

LNS: 100HZ AUHipass filter applied to first segment.
