Atlapetes, Apr. 13, 1961, V.   (47)

Incidentally - I forgot to mention - but I suppose that most of the "Ta-zeeeeeeee" Notes I heard today (at least the ones without the rattle undertone) were the same as the notes I transcribed as "ta-seeeeeeeee" and "tuh-teeeeeeeee" before.

 Atlapetes, I.

April 14, 1961
Cerro Punta

This morning I watched the same pair of Chestnut-capped Atlapetes as yesterday.  Behaving in much the same way as yesterday.
  
One bird became separated from the other while they fed. (It flew across an irrigation channel). The bird which left its mate then started to utter "songs."  Quite variable, but mostly comme ça:
  
"Ta ta zeeeeeeeeeee ta-ta."
   
The last notes (the "Ta-ta"s) were usually louder than the rest (and lower pitched than the preceding long note.)
  
Sometimes the bird uttered "abbreviated" songs. More or less comme ça: "Zeeeeeeeeeeee Zeeeeeeee"
  
There was a faint rattle undertone to some of the "Zeeeeeeee" Notes in both types of songs.
  
All these songs were accompanied by some CR and Thflff - but this may not have been very significant (the birds always seem to have some CR and Thflff whenever I see them).
  
As in the case of Pselliophorus (see today's notes on P.), I wonder if the long "Zeeeeeeeeee" Notes in the "songs" of the chestnut-capped Atlapetes are really essentially SN's?
  
Later in the morning, the 2 birds of this pair of chestnut-capped became separated again. One of them immediately began to sing, more
