a) 8:00 PM. Weather: Fair. These birds were heard singing back in the woods. I played the field tape and they came quite close. Quality: 2. & 1-2. Level: +10.
First we hear the bird with higher voice (female), then the bird with lower voice (male).
Then the birds had left but I called them back again with the field tape.
(Also heard are C. virgata and O. guatemalae.)
Then I collected the low-voiced bird = male #5077.
By playing the high-voiced bird from the field tape, I brought it back again. However, it left before I was able to get it to a good position for collecting.
9:45 PM. Weather: Clear but very humid. Then much later it returned and I recorded and collected it (= female #5078).
Incidentally, these birds have brown irises and their eyes do shine in reflected light at night.
