Then song and growls. Although the bird reacted to playback, it didn't come to me. Therefore, I finally moved much closer to it, recorded its song and growls. I tried playback of field tape. This bird did react to C. plumbea (of Rio Grande) but was not at all attracted to C. subvinacea (of Rio Grande). This bird was then collected = (male #4794). Quality: 1-2. Level: +5.
