Mixed Diglossini, Apr. 18, 1965, V 

[[left margin]] Laf Humer [[/left margin]]
Laf still feeding quietly original Humer area. Looks as if it has definitely managed to dispossess the Humers. (Off and on this morning, I have noticed 1 or 2 Humers in scrub and small Eucalypts between this original Humer area and the Primes. Perhaps these are the birds that used to own the original Humer area. Perhaps they have just moved down the line a bit.

[[left margin]] Laf IV [[purple]] 14 [[green]] [[/left margin]]

7:58. Single Firebelly ✓ [[green]] flies into the in which Laf ✓ [[green]] is feeding. As far as I can tell, the 2 birds ignore one another. But then fog comes in again and I lose sight of them again.

[[left margin]] V [[purple]] 21 [[green]] Ruf Laf Ruf Laf [[/left margin]]

Well! Well! 8:05am. See definite mixed flock. Moving thru dense natural scrub between Laf territory and Primes. I cannot see all the birds. But the group definitely includes 1 Firebelly ✓, 1 Ruf ✓, 1 White bearded fly catcher ✓, 1 Black Diglossa ✓ (almost certainly Laf), others ✓✓✓. All ranging 2-6 ft above ground. Firebelly staying in higher range relatively more than others. Ruf following. Firebelly, Laf, and/or White-beard in lead. Possibly one sooty gray thrush on outskirts flock, but only for a few minutes. No sounds of Atlapetes in neighborhood.
[[all checks in above paragraph are green checks matching green 21]]

[[left margin]] Ruf 92 [[red]] [[/left margin]] 
8:28am. Go on uphill a little. Find single Ruf ✓ feeding low, rather sparse, natural scrub. 1-3 ft above ground. Probably same bird that was with group earlier, but now definitely alone.

[[left margin]] Ruf [[/left margin]]
Ruf certainly is not an obligate commensal like sitticolor ssp! 

[[left margin]] Humer 93 Laf [[/left margin]]

8:32. See single Humer ✓, alone, passing thru area where Laf was earlier.

[[left margin]] Humer [[/left margin]]

Fog lifted somewhat 8:42. Humers still chasing one another, and hummingbirds, in Primes.

[[left margin]] 94 [[/left margin]]

8:45. Pass area where flock seen earlier. White-beard(s) ✓ (still)
