These are probably some of same birds recorded in Cut E-6.
First is a type 2 phrase, probably same bird as in E-6, a; original recording. Quality: 2+. Level: +3.
Then another phrase same bird, filtered 600/2.5kHz as are all succeeding recordings until noted again. Quality: 3 to 1-2. Level: 0. Copy N-IV to N-4.2; filt. 500/2.5 kHz.
Types 2, 2-3, 1 are heard.
The last four phrases of type 1 are then added here as the original recording. Quality: 2 to 1-2. Level: +3.
The birds were not as concentrated today as they were yesterday at this time. However, as yesterday, they stopped singing ~5:20 PM. But then between 6:30 - 6:40 PM they all sang again, but I had the impression that they sang with less volume than normally.
