Mixed Diglossini, Oct. 27, 1962, III 

[[eft margin]] Humer Laf [[/left margin]]
outbursts damper area. Sing from time to time. Again no overlap with Lafs. Correction: 1 Laf begins to sing just after Humer begins. But Laf shuts up soon, Humer continues.

[[left margin]] Cy [[/left margin]]
There also seems to be a Cy in this area. Sings when both Lafs and Humers are silent.

[[left margin]]  Laf [[/left margin]]
Songs of Lafs very indeterminate. Perhaps basically "zee-zee zaa-zaa zee-zee zaa-zaa....." but quite regular. Notes not always in doublets (I think single "zaa"s may be particularly common). Some long and apparently high intensity Laf songs contain brief R's! "Zreeeeee"s [[waves drawn under e's]].  Not in doublets, I think. Scattered toward middle song phrases.

[[left margin]]  Laf [[/left margin]]
All diglossine song becoming less frequent now 7:00am.

[[left margin]]  Laf [[/left margin]]
7:06 Laf joins (attempts to supplant?) unidentified XXV. Quite silent

[[left margin]]  Laf [[/left margin]]
7:07 2 Lafs join or attempt to supplant pair of furnariids. Largely silent, but one burst song. Then fly away.

[[left margin]]  Laf [[/left margin]]
I am now fairly convinced that when Lafs join other species they are eventually hostile.

[[left margin]]  Humer? [[/left margin]]
Some Humer songs here do not have R components 7:16

[[left margin]]  Laf Humer [[/left margin]]
There certainly does seem to be nearly or completely perfect territorial segregation between Lafs and Humers here.

[[left margin]] Cy Laf [[/left margin]]
7:20 Pair of Cys suddenly appears in middle Laf territory. Feed (on tubular red flowers) and sing in several small trees & bushes, including at least one in which the local Laf has sung and fed. Then Cys j----> furnariids. Then Cys fly away. Then the local Laf appears, (he was not visible before this), flies after Cys. Both species
