(In latter part gain reduced 15 db, then increased from there by 10 db; bird had meanwhile moved a little farther away.
Note: From km 20.5 (concrete bridge) I could hear this km 23 bird at 5:30 AM and from this km 23 site I heard quite well the bird ca. km 20.5; some of the latter may even be heard in Cut 16 (especially in middle part) in spite of the high noise level from foliage drip.
