[[circled]] 5 [[/circled]] Mixed Diglossini, Sept. 29, 1962, II. [[left margin]] Laf [[/left margin]] Another brief burst Laf songs 6:04. Again obvious how birds stimulate one another. [[left margin]] Laf [[/left margin]] Single Laf singing in exact area where Rufs were n.b. yesterday. Hear an outburst "wren-like" song while 2 Lafs hopping about in bush together.
