媒体文件注释

Dawn song -- this was the last recording before the birds stopped singing, so ends at 6:22 a.m. The deeper voiced bird sang more often. In the middle of the recording, the higher pitched voice doesn't reply for a little while, but then resumes. The first and the last voice heard on the recording is the deeper, lower pitched, voice..

观察细节

They were "singing" when I arrived at 5:55 a.m. The two voices were of different pitch, sometimes following, sometimes singing at the same time, which made it seem like a duet. The last songs were at 6:22 a.m.and the diurnal birds began to sing at 6:26 a.m.
