To make matters more confusing, Grantsau (1968) described, as already stated, the upper tail-coverts in P. nattereri as uniformly chestnut-reddish in colour. P. maranhaoensis, in contrast, is said to have bronzy greenish feathers with chestnut-reddish margins. Examining the 12 skins of P. nattereri, I discovered this latter coloration in all specimens, but not a single bird had uniformly chestnut-reddish upper Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the orig
