Atlapetes, Mar. 28, 1960, II 

Mar. 6, 1959, p.3!  Most of their basic phrases had a little terminal bit added. Sometimes just a single "be" or "tee" note. Sometimes a partial duplication of the end of the basic phrase, i.e. "be beeeeeeeuu" or "tee teeeeeeeeeee"  Perhaps

Sometimes a brief triple note which David would transcribe as "titawheeeeeeee" ("tuh-ta-teeeeeeee"?). More often a double
"tit wheeeeeeee" ("tuh-teeeeeeee ?) (This latter double note was sometimes also uttered independently, apart from the basic phrase.) David is fairly sure that all the songs, at least those ending with a fairly long note tended to become lower in pitch at the end. I.E. the last note tended to become lower in pitch at the end.
   
All their songs were definitely stronger and more whistling than the songs of the Yellow-throats.
   
I only saw the bird actually singing once. Sitting with head & bill pointed diagonally upward, but with little or no CR or Thf.

possibly slight trace of CR, but no more than this.
   
Their songs were also intermingled with quite a lot of CN's. Apparently perfectly ordinary CN's. More or less "Tsit"s.
