[[circled]] 55 [[/circled] Tangara, March 26, 1961, IV no display by either bird before or during the feeding or transfer of n m.; but the male flew away from the female with typical CN Trills. The male is marked with an aluminum band, while the female is unbanded, so that the 2 birds can be told apart without difficulty. I watched the A birds building again this evening. I have now seen their building long enough to be able to say that the male never, or almost never does any actual building himself. All I have ever seen him do is give n m. to the female, and even this is relatively rare. The head shape of this species, at least when the birds are relaxed, is comme ça: [[image - sketch of bird] this nape curve sometimes longer and more rounded. Tangara, I March 27, 1961 Barro, Colorado I have now decided that pair A is not the pair which had the nest right beside my house a few days ago. The A birds were followed by two other, presumably young, Plain-coloreds this morning. This morning there was also another pair, in an area nearer my house, which was attended by a single other bird. I think this latter pair must be the one which had the nest by my house. If so, this means that I have heard "Sreee" notes uttered by birds of two different pairs. The A birds behaved in much the same way today as they did yesterday and the day before. But perhaps they built a little less frequently
