Cyanerpes [[underline]], Feb 5, 1958, II (39)

tanagers (1 Blue and 1 Summer) in the same tree. I couldn't see what this posture eventually led to, as the pair eventually moved behind some leaves.
Earlier this afternoon I saw what was presumably a different [symbol for male) showing traces of what was probably the same pattern beside the Balia Tree near Chapman House. He was apparently single, sitting quietly most of the time in a more normal posture than the one [[?]] above -- except that his black hood was more or less "swollen" most of the time/looking almost like a t...our. This bird also left before I could see if some more overt behavior could develop.

I saw a little more usual hostility during another incident at about the same time. A [symbol for female] landed right near a [symbol for male], who immediately when into a "Wh couples" performance, with extremely vertical ft but not very extreme other components, and with 2 notes which seemed to be intermediate between typical HCN and typical HAC. [Symbol for male] relaxed quickly as the [symbol for female] ignored him and started to preen in the usual way. [[image: bird with dark wings and nape, head thrown back in vertical posture] (Posture comme ça, with no trace of wing-quivering or wing-flashing.)

I seldom or never seem to hear any ordinary CN's during my observations of wild birds. Is this just because they are relatively faint? I wonder. I suppose so.
