SEE TODAY'S NOTES ON GENERAL MIXED FLOCKS

[[footnote 1]] 7:17 a.m. 10,150 ft. Near Humer R's and R-Zaza's in AS Also 1 brief Humer Song. NODWAH

[[footnote 2]]  NOTE: This area, as a whole, [[underlined]] seems [[/underlined]] to be about as poor in Diglossini as anywhere I have ever been. Possibly the birds are just "hidden".  If so, they probably are [[underlined]] not [[/underlined]] in breeding condition (altho species of other groups may be).

[[footnote 3]] When see Rufs with flock which also includes White-spectacled Whitertarts (discovered elsewhere). One or both Ruf(s) utter(s) an appreciable number of Twitters from time to time. Usually or always as "Greetings".  [[underlined]] Not [[/underlined]] overlapping White-spectacled songs.

[[footnote 4]] Twitters rather variable in form. All rapid, [[underlined]] loud [[/underlined]], and clear.  At least one Twitter is a "completely" formless warble — quite like a loud version of the Twitters of Cys [[underlined]] without [[/underlined]] Intro Notes.  Another Twitter begins as a formless warble but ends with 2 or 3 quite distinct "Zaawee" Notes.  Grauution between initial formless phase and terminal "Zaawee" phase is gradual (but rapid).  Another Twitter include a formless warble, followed by 2 or 3 "Zaawee" or Zaa-a-wee" Notes, followed by another brief formless warble, and ending with more "Zaa-wee" or "Zaa-a-wee" Notes. (Again transitions between different phases are gradual but rapid.)
  
[footnote 5]] It would appear that the Ruf Twitters include notes which are nicely intermediate between "typical Diglossa doublets" and "typical Conirostrum triplets"!!! ([[underlined]] This may be further evidence that Diglossa and Conirostrum really are closely related. [[/underlined]]
    
[[footnote 6]] As far as I could tell, the Ruf Twitters were [[underlined]] not [[/underlined]] accompanied by any special postures or movements.
