7:01 am. See single [[underlined]] Tangara vassorii [[/underlined]] (Blue & Black) feeding in low scrub edge pasture. Uttering CN's There may be other birds with it; but I can't see them.

7:12 See single new [[underlined]] Basileuterus [[/underlined]] type (LXXX) in tangles edge pasture. Uttering brief, hard, loud R's.
 
Then see Blue & Blacks fly into tall tree, Lands near large flycatcher, but the 2 birds seem to ignore one another.

Then see mixed flock. At least 2 BCBT's, 1 wren or furnariid. BCBT's uttering lots of R's. All in tall trees 30 - 60 ft above ground. BCBT's f [[right arrow]] wren or furnariid. But then the latter move on, and the BCBT's apparently do [[underlined]] not [[/underlined]] follow. 

Some minutes later, in another area, hear lots of noise. Including BCBT R's. Apparently several species
involved. Then a pair of BCBT's flies away from this area. Down hill across road. Noise, including BCBT R's continues uphill. Down hill BCBT's eventually fly back uphill to join the noise. This presumably is BCBT boundary dispute. One pair eventually flies away down hill (again). Uttering lots of R's Definitely not followed by anything else. 

Considering how noisy this dispute is, it is remarkable that it is not attracting individuals of other species. 

Leaving this area 7:45.

Arrive new area, past Las Cuchillas 7:57. 7600 ft according to my altimeter. Area partially cut down forest

Can hear White-spectacled Whitestarts singing. Quite Laf-like here. 

8:23  A single [[underlined]] cyanocephala [[/underlined]], all by itself, flies from tree top to tree top.
