October 20, 1963
La Paz

Working in the usual abandoned garden area this morning. It was my impression that the local thrushes, [[underlined]] bonariensis[[/underlined]], and Orange-billed Saltators were less vocal today than yesterday. Possibly because it was cold and damp.

Working in the Myst region above Unduavi this afternoon 11,250 ft. Fog & rain as usual. Arrive 3:22

[[margin in red]] Myst [[/margin]]
3:25 pm. Come across mixed flock in very [[underlined]] thick [[/underlined]] fog. Includes at lease 8 ^[[8 check marks above]] warbler-like small birds; but I can only identify 3. 1 Myst, 1 Orange head, 1 Black & Orange Stripe. All moving thru thick scrub, 2 - 6 ft above ground. Some or all uttering lots of "Tsit" CN's. I don't know who was leading. Certainly [[underlined]] not [[/underlined]] the 3 birds I identified. Flock moving slowly, but fairly coherently, in one direction.

3:55 pm. Come across a group of at least 3 jay like birds moving along tops dense scrub 10 - 15 ft above ground. Too foggy to see them clearly.  Uttering nasal caws or whines, and probably whistles. Apparently alone. Not accompanied by other species.

[[margin in red]] Myst [[/margin]]
Incidentally, the Myst area is just about 1/2 - 1 KM short of the 50 KM (from La Paz) road marker.

[[margin in red]] Sitti [[/margin]]
4:10 pm. Heavy fog again. Come across a ^[[4 check marks above]] small flock of warbler-like birds. Includes  ^[[1 check mark above]] 1 Sittiz and at least 1 Basileuterus. The latter of the XLI type; but which species it was, if there is more than one species in this region, I don't know.  Birds uttering a few "Tsit" CN's In dense scrub, 6 ft above ground. Not moving very much.
