Mixed Diglossini, May 23, 1966, III [[circled]] 66 [[/circled]] 8:27. Hear what may be Diglossine Twitter in distance. Completely overlapped by Scan Song. [[margin]] Bari Scan [[/margin]] Aha!!! 8:42. A couple of hundred yards away. See single [[male symbol]] Bari (definite) feeding low in scrub. 1-3 ft up. Definitely alone. Feeding on pinkish-red flowers. [[underlined]] Not [[/underlined]] one of the species on which Scan was seen to feed earlier. This area certainly is adjacent to a Scan territory; but I have not seen Scan in exact same place. [[margin]] Bari Scan [[/margin]] Bari utters several R's (pure, rather high pitched trills, without any other component). At first overlapped by Scan Song. Then Scan shuts up. Bari utters 1 or 2 more R's. NODWAH. Then shuts up. Disappears. Scans resume singing. NODWAH. [[margin]] Bari Scan [[/margin]] 8:50. [[male symbol]] Bari reappears same area. Alone. Feeds 1-2 ft up. Utters several R's. All completely overlapped by Scan Songs. [[margin]] Bari [[/margin]] NOTE: This individual does not have any obvious white marks on tertiaries or anywhere else. Again Bari flies off. [[margin]] CC Bari Brun [[/margin]] NOTE: This patch of scrub looks quite suitable for CC's. But they do seem to be absent. Similarly, the area worked earlier looked quite suitable for Baris; but I didn't see or hear a trace of them. [[underlined]] Both [[/underlined]] areas look quite suitable for Bruns. [[margin]] [[underlined]] Gen [[/underlined]] [[/margin]] All this is (further) evidence that the Diglossines of this region [[underlined]] tend [[/underlined]] to be [[underlined]] ecologically separated [[/underlined]]. [[margin]] Scan Bari [[/margin]] 8:58. Scans silent now. Hear more Bari R's. NODWAH. Then hear Bari R's coming from some distance away. Also NODWAH. So there may be at least 2 inds. of the species here. Then hear more Bari R's down road. Apparently, there
