[[underlined]] Diglossa [[/underlined]], Aug. 7, 1959, III.  [[circled]] 10 [[/circled]]

[[blue lines running down left margin of page]]

[[male symbol]] II stopped displaying immediately and returned to the center of the bush, out of sight, presumably to relax. (At this time, I thought that [[male symbol]] II must be a [[female symbol]] or a juv.; but when I finally located him again in the same bush, I got a good view of his plumage)  Eventually [[male symbol]] II came out again and started to feed normally.

Then another bird gradually approached, by short flights, from a distance. This was presumably [[male symbol]] I; as he eventually went to feed in the bush where I first saw the 2 birds, and stayed there for a little while at least. When [[male symbol]] II first saw [[male symbol]] I approach in the distance, he first fixated him intently, and then gave a brief soft "Brrrrrrp" Note. Presumably a form of R. Then started to feed again. As [[male symbol]] I came still closer, II continued to feed, but uttered occasional WHAC notes during the feeding. Interestingly enough, he did not do any BU while uttering these WHAC's. The WHAC's themselves, however, were quite similar, nearly identical, with the WHAC's uttered with BU. They were of the "Whaa-aash" type; and it was my impression that the "sh" sound was much more conspicuous in these circumstances than earlier

All this hostile display is most peculiar. Certainly not reminiscent of [[underlined]] Cyanerpes - Chlorophanes [[/underlined]]. Perhaps more like [[underlined]] Coereba [[/underlined]]???

When I go back again to look at males I and II again, after an hour, I find that they are still continuing their dispute. In [[male symbol]] II's bush (At least, he seems to consider it his bush; although [[male symbol]] I seems to feel some degree of possession over it too.) Much as before. I not displaying II doing frantic WHAC and BU. This time I could see the BU better. The waving and Q-like movements of the wings are really balancing - definitely not integral parts of the display. The head, throat, breast and belly feathers are very ruffled. The tail is partly spread during all BU, but is suddenly spread
