Atlapetes, Apr. 15, 1961, IV 

always with a strong lateral component.  When moving about normally (undisturbed), the birds perform few or no WF's (I imagine, however, that the species may perform WF's when "upset" - like other bush-finches.)


Atlapetes, I.
April 16, 1961
Cerro Punta

I went back to the same place again this morning. Arriving early, around 6:10 a.m. When I arrived a Yellow-throat was uttering "dawn song" in exactly the same spot I first heard the "dawn song" yesterday. The bird was very well hidden, and I never even caught a glimpse of it. The song itself was exactly the same as the one I heard yesterday. "Kew"s definitely higher
pitched than "Keeyah"s I finally flushed the singing bird, without, however, actually seeing it. Then, a few seconds later, I heard a Yellow-throat uttering the "dawn song" in exactly the same place I heard the second burst of singing yesterday. But again I was unable to see the bird. It finally stopped singing without my ever catching a glimpse of it.
  
Then, a few minutes later, at 6:37 a.m., I saw a Yellow-throat perched in a quite high exposed position (about 15 feet off the ground) uttering a few "scattered" "Kew" and "Keeyah" Notes. Comme ça: "Kew.........Keeyah........Kew Kew..........Keeyah......." Presumably the lowest intensity version of the dawn song. With CR and Thflff. Bill opening & closing with each note. No WR. One WF with one of the notes. Then the bird flew away without doing anything more.
