[[circled page]] 24 [[/circled]] Approximately a minute later, see single Blue Diglossa in same bush. [[margin, in red]] Cy 16 [[/margin]] Almost certainly [[underlined]] Cy [[/underlined]] [[pencil and red checkmarks]]. Silent and alone. Flies off, [[margin, in red]] Coer [[/margin]] past tree in which Coer is still singing as before. Cy passes about 30 ft below Coer. [[margin, in red]] Cy Albi Coer [[/margin]] So Cy and Albi territories seem to overlap here (I think I established this in 1962). Cy and Coer territories may also overlap. Shortly after the Cy flies by, the nature of the Songs from the fruit tree [[underlined]] appears [[/underlined]] to change. Intro notes become more like "soooo", and become relatively louder. And the twitter part of the Song phrases [[margin, in red]] Coer? [[/margin]] becomes more Cy-like - very much like the shorter Cy phrases at the Paramo de Guasca. I think that a Cy [[underlined]] must [/underlined]] have gone up in this tree [[margin, in red]] Cy? [[/margin]] and begun to sing. But I can't see the bird. When these Cy-like phrases begin, the typical Coer phrases stop. No overlap. If there was a Cy in this tree, it did [[underlined]] not [[/underlined]] feed on fruits. [[margin, in red]] Cy? [[/margin]] I would have seen it moving if it had fed. Anyhow, a few minutes later, the Cy type phrases stop. [[margin, in red]] Coer [[/margin]] Typical Coer phrases begin again. And now I see an undoubted Coer feeding on fruit again. Also definitely see that this is the bird which is uttering the Coer-type phrases. See mandibles moving. [[margin, in red]] Coer Cy [[/margin]] The Coer has been ranging 25 - 40 ft above ground in this tree. If there was a Cy in the tree, it stuck to 20 - 25 ft level. [[margin, in red]] Coer Cy [[/margin]] This evidence, such as it is, fully supports the hypothesis that the mutual avoidance, inhibition, mechanisms are fully operative in the Cy-Coer relations here. [[margin, in red]] Coer [[/margin]] 8:00 am. Coer still in tree. Still uttering typical Coer type phrases
