    Equipment Note

NOTES: Calls from adults and nestlings. Good quality.

[This appears to represent almost exclusively calls by nestlings. The quality of these calls is more adult-like than those in LNS #106545, combining loud "peeping" (see Figure 6E) with calls quite similar to the Short Rattles of adult birds. Based on BNA account, these birds were near fledging age (about three weeks). Contrary to announcement, I suspect the Short Rattles were given by one or more of the nestlings because the young birds did not seem to react to this call as I suspect they would have had a bird been coming to feed them, and these calls appear to grade into the Begging Calls in numerous instances (e.g., 0:11-0:41). Another possibility is that there was a recently fledged juvenile returning to the nest with its siblings. An adult bird can be heard giving Short Rattles in the background, often in the distant background, at 12:365, 13:29-13:42, 14:465, 15:095-15:365, 24:215, 24:39-24:49, 31:02, 31:07, and 31:12. Also in the background is a Drum at 28:49, a Rattle at 28:535, and a series of Kweek Calls at 30:31-30:34. The adult bird apparently arrived to feed the young at 13:44 and 23:59. Quality changed from 1-2 to 1-2, 2 (some parts have quite a bit of wind noise and the young are rather quiet in others, but this is generally quite good) - CAM - 20 April 2005]
