do not follow.

[[left margin]] Humer  Laf [/left margin]]
7:30. Now, I think I can hear another Humer, way uphill, uttering same type song phrases as first one. And there seem to provoke the Laf to sing. Large overlaps. Then Laf shuts up. Humer continues. Then first Humer sings again. Both Humers overlap, Then Laf sings again. Overlaps one or both Humers. Then all shut up. 

Going a little uphill 7:35.

[[left margin]] XI [[in purple]] 41 [[in green]] [/left margin]]
See a White bearded ✓ [[in green]] Fly catcher f ––––> Firebelly ✓ [[in green]] in flight. 

[[left margin]] Cy Humer 137 [/left margin]]
7:40. [[?]] Cy uttering song phrase after song phrase. There seem to stimulate Humer to sing in distance. Complete overlap at first. Then the two birds alternate a few phrases. Then the Cy shuts up. Humer continues for a minute or so. Then shuts up also.

[[left margin]] Humer [/left margin]] 
Now I think I hear other Humer(s) in distance. All phrases with little or no R. When there is a trace of R, it is terminal. The whole population of Humers here seems to be in vouie[[??]]! 

[[left margin]] Humer 141 [/left margin]]
See several more single Humers. Then see 1 Humer land about 10ft from another. Faces the others, raises tail diagonally, without uttering a sound. 

[[left margin]] Humer [/left margin]]
It is interesting that none of the TU patterius seen here have been accompanied by any trace of BU. Is this a diagnostic character of Humer??? (BU = Bill up?)

Hear what sounds like Dubunia[[??]] in distance.

[[left margin]] Laf Humer [/left margin]]
You know, I am not sure that the territories of some Laws and some Humers do not overlap in this region. Very difficult to tell, because birds always seen so briefly. Certainly, if the territories do not overlap, they are crowded together. And there may be occasional trespassing when the owners are away.
