[[underlined]] Diglossa, [[/underlined]] May 24, 1961, VI.

[[image: diagram of cadence]] "Zeewa zeewa zeewa zeewa zeewa  zeewa zeewa  zeewa zeeyooooo"
(All [[underlined]] very [[/underlined]] rapid).

It is possible is that the songs of the Nono birds are characteristic of a later phase of the breeding cycle then and other songs of the Atacaso birds.

Like this evening;  I saw another song-aerial flight performance.  A [[male symbol]] flew up, about 10 feet above the level of the shrubbery, and then down again, singing all of the while.  His song was quite ordinary, quite like the songs of other birds singing on perches here.  The course of his flight was comme ça:

One [[male symbol]] [[underlined]] aterrima [[/underlined]] repeatedly supplanted a ([[female symbol]]) [[underlined]] Diglossopis [[/underlined]] feeding in the same tree.  He uttered a few songs during the period he supplanted.  One quite ordinary.  A couple of others even more hurried, and probably briefer, than usual.

[[underlined]] Aterrima [[/underlined]] [[male symbol]]'s seem to have two types of "CN".  "Tsit"s and "Seet"s.  I don't know what the difference between them is yet.  "Tsit"s more hostile?  Or more aggressive?

Have requested advice from Smithsonian on how it wants Moynihan's colour & pattern coding transcribed.
