Song type 1 = SO-SOO-la; 2 = SO-SO-LA; 3 = SO-LAA.
Date: 15 to 16 May 1973. Time: 9:10 PM to 12:25 AM. This is very probably Bird #1. There has been no further imitation; the bird is "singing in its sleep." Quality: 2+. Leel: 0. 139 tape. 3.75 ips. Std. Orig. recl @ 7.5; copied N-IV to N-4.2, filtered 100/3000 Hz.
Bird sang in "groups" of 3-5 phrases with long silences between.
12:40 AM to 2:30 AM. Due to some intervening obstruction, I wasn't able to obtain [a] clear, direct focus.
The bird remained in exactly the same spot throughout the night. Up to the time it rained at ~ 5:00 AM it continued to sing periodically. Quality: 1-2. Level: +3. 175 tape. Std. 7.5 ips. Original recording.
Although bird #1 is a type 2 singer, the three figures of its phrase are slurred together. Whether this is real, or an artifact due to sound reflection from the surroundings, I'm not sure. At times its phrase seems contracted to almost a type 3 phrase.
Try to find a phrase among the recordings that is a well-defined type 2, with breaks between the figures, and compare it (sonagram) with a slurred type 3 and an intermediate.
