Here in Lolldaiga Hills, ca. 30 km NW of Mt. Kenya, I have only seen all black individuals....and I have the impression that at least some of these are present (resident) during all months.
 
The one exception was a few days ago (15 July 2014) when I observed my first individual here with yellow shoulders (in fever trees along a lugga at 1,800 m).  I have been working at this site for almost a year now.  I suspect that this individual is a migrant.

My experience is this is a visitor here.  In time when I've been around for months I have only seen it seasonally - this one was all black male and will check to see if I have seen yellow shoulder patches before. Will also look up Moreau s work.

Hi Nobby

a cold season migrant with you ?

but where from ?

what did Moreau have to say about it ?

we have a small breeding population "up north" and perhaps one in southern Tanzania as well but most of our birds are surely from even further south.

Peter Britton wrote this bird up for Kenya and I recall Prigogene wrote about it for the DRC. I'll dig out the references.

I'll put a map together today.

this from Britton (1980).

This and the following two species are regarded as races of C. phoenicea by White (1962b) but we follow Hall & Moreau (1970) in treating them as separate species within a superspecies. A wide-ranging and seasonally common bird of wooded and bushed habitats and forest edges up to 3000 m, north to the Lake Victoria basin, the highlands and peripheral lowlands of W and C Kenya, the Tana River and Lamu, including Zanzibar and Mafia. The few breeding records are from 900-1700 m in Kenya and N Tanzania, but it probably breeds elsewhere, particularly in S Tanzania. In Africa as a whole it is virtually absent from plateau country south of 70ºS during the dry months of April-September, moving north and east after breeding, exceptionally north to the Lake Turkana basin. Some East African populations are probably resident, but numbers are apparently augmented by these southern breeders. About half of the males in several areas of Kenya and N Tanzania have yellow shoulders. Most males are entirely black in many localities, especially in C and S Tanzania and S Uganda.
The arrival of entirely black non-breeders is very apparent in parts of Kenya, particularly at the coast and Kabete.
