Mixed Diglossini, Feb. 28, 1964, I
[[circled]] 54 [[/circled]]

songs other lafresnayei ssp, but probably even slower and more deliberate

[[left margin]] Myst [[/left margin]] Then, 6:55, 10,825 ft, hear another burst of such song. Stops fairly soon. Then I see an adult Myst. Perched exposed in dead tree 15-20 ft above ground. Silent when I see it, but this is exactly where the song had been coming from. Obvious that this is the bird that sang.

The dead tree is just on the border between thick, apparently virgin scrub and thinner, apparently second growth scrub. Near patch open grassland. And the bird eventually flew down into the thinner scrub.

This bird's songs did not overlap with those of any other species.

[[left margin]] Myst Sitti B&C [[/left margin]] From sound alone, I would imagine that Mysts are not uncommon around here. And there seems to be no other diglossine around in the neighborhood now. (Altho this is not too far from where I saw Sittis - and conceivably C. ferruginiventre - with mixed flocks during my last visit.)

[[left margin]] Myst [[/left margin]] 7:17 am. Hear more Myst song in adjacent area. Possibly by same individual. Again no overlap with any other species. (Everything else seems to have stopped singing some time ago.)

Mysts seem to be singing more frequently now than during my previous visits

Considerably further on, 10,950 ft., hear more Myst songs. Two birds singing simultaneously. Complete overlap. 7:33 am. Scrub rather patchy up here.

[[left margin]] Myst [[/left margin]] Song of these Mysts is much slower and more deliberate than that of local Whitestarts.

Again no overlaps songs other species. 

Still further on, more Mysts singing 7:45. In thick scrub not far from open field. Unfortunately all birds invisible
