    Equipment Note

NOTES: At A-time 4406 wing/feather noise when bird comes into land on fence post. Filtered at 250 Hz. [Eleven songs and song fragments of two or three different song-types are apparently given by at least two different individuals. Song-type by one bird appears to change at 0:20, 1:09, and 1:27, but the two song fragments given at 1:30 and 1:42 were clearly given by a second bird. In addition to the songs, there is a series of what appear to be "See-You" calls by a Bobolink at 0:25-0:48 (confirmed by Dr. Jean L. Woods, Delaware Museum of Natural History) "Buzzes" at 0:15 and 1:07-1:09, and a "Chunk" Call at 1:26 appear not to have been given by the individuals that were singing. The "check" calls at 0:59 and 1:00 are those of Agelaius phoeniceus. Quality changed from 1 to 2 - CAM -12 October 2005]
