[[ circle]] 59 [[/circle]] Flock as a whole is [[underlined]] quiet. [[/underlined]] But, I hear both Cy and Coer singing, at different times, in general vicinity. Both NODWAH. The 2 birds probably are not close together. Coer heard only toward rear of flock (approximately same place where Coer heard yesterday afternoon.) Cy heard only toward front of lock. Certainly neither was near Inter. A single sooty thrush was in center of flock for some seconds, but I don't know if it continued to associate with group or not. NOTE: This is yet [[underlined] another [[/underlined]] area where White-spectacled Whitestarts apparently do not reach high altitudes. 9:52. Catch up with same flock a little further down road. Certainly includes at least 2 Juters. Leaving 10:00 am., as rain starts again REMARKS: I. Altho the flocking behavior seen this morning was [[underlined]] very [[/underlined]] reminiscent of the Western and Central Cordilleras of Colombia, [[underlined]] I am still not convinced that Allogregariousness is generally as highly developed here as in the latter two regions. [[/underlined]] II. Certainly the flocks on Pico Espejo and Paramo La Negra differ from those of the Western & Central Cordilleras [[underlined]] in form [[/underlined]]. I.E. They are smaller, on the aver. They also may tend to be less coherent and/or quieter. Especially in the non-breeding season (April). III. Altho flocks such as those seen this morning are similar to those of the Western and Central Cordilleras in form, [[underlined]] such flocks seem to be absolutely confined to regions of very extreme humidity in this region. [[/underlined]] I am sure that I have seen equally extreme flocks in regions of lesser humidity in parts of the Central and Western Cordilleras (e.g. parts of Purace). IV. But I am beginning to come to the conclusion that the "frontier effect", [[underlined]] everywhere, [/underlined]] may be primarily an adaptation to hum
