You may be right, Mike L, and I may have made the strategic error of only referring to MacKinnon, for a verification that Pale Blue can look like this.
But I've got to say it doesn't look right for Verditer to me, either structurally, or in terms of tone (obviously potentially not represented "accurately" by photography).
The illustration of Pale Blue on Plate 80 in MacKinnon does indeed look like this, and other texts such as Rasmussen (BoSAsia) refer to a "scaly vent". And the greyer throat and underparts look right and are borne out by other texts (eg Robson).
It really would be nice to know where we might go to look for it.
