Atlapetes, May 24, 1961, IV.

I saw one particularly interesting incident at Iñaquito on May 22. One rufinucha was singing in a hedge. Then he suddenly flew up, uttering "Tsit tsit tsit ...." or "Tuk tuk tuk ...." Notes, and flew to a bush several yards away, where he landed beside another rufinucha. Unfortunately, I couldn't see the birds in the bush; but I heard a lot of "Zeeee" Notes & R's coming from the bush immediately after the [[male symbol]] landed. Then the [[male symbol] flew up, perched in a tree above the bush, uttered one long R, and then flew back to the hedge, with "Tsit"s or "Tuck"s as before. A few seconds later he began to sing again.

This incident might suggest that "Tsit"s are just plain hostile.

Observing near Nono again this evening.

I heard 2 more "greetings" between the members of pairs of rufinucha. Definitely 2 different pairs. Each time the "greeting" was uttered by only one bird of the pair, when one bird landed beside the other. I was not able to tell if it was uttered by the landing bird or the bird landed beside. Both greetings were essentially similar "zee wee zee wee zee wee zee wee". One much louder than the other.

I should stress that these "greeting" notes were quite clear and hard. Almost semi-R. Not at all hoarse. I.E. such "greetings" are probably not strictly homologous with the GHAC of other species.
