First natural song. (The rhythm of this song is somewhat different, especially at start of each phrase.) Quality: 2; Level: +5.
Then bird closer, very likely after playback but not noted so in field. Quality: 1; Level: +2. This bird was then collected (male R.G. #5869). Note: I have rechecked this skin and it is definitely D. certhia 27/VIII/68 PAS
