Fig. 7. Views of the upper Río Corocoro valley, from the slope above the 1700­m camp (see arrow in fig. 6, bottom). Top: Looking northeastward (upstream) toward the Colostethus locality on far side of river. Bottom: Looking southeastward to helicopter about to sit down in the streambed at camp. The hillside above the 1700­m camp is covered in Tyleria­Stegolepis­Brocchinia scrub growing on rocky soil. Peering uphill (looking for the cameraman who had just called to him), ornithologist George Barrowclough provides a sense of scale for the density and height of the scrub vegetation. See figure 23 for interior views of the mossy gallery forest across the river.
