Hmmm, for some reason I read the description wrong and thought it said that the species stood out for its bold colours. This is perhaps because in most online images, the species shows quite fulvous/tawny underpart coloration. The cheek and lores show similar tones, although this is more pronounced in East Africa, it seems. The crown, on the other hand, is not contrastingly rufous except from the front angle. I thought Chattering is a better match, although I can't explain the pale lower mandible (maybe it's a juvenile?) or the warm tones on the underparts, and I could be wrong.
MacNara: Any experience with these two?
Hi Andy.
I'm a bit embarrassed that you ask for my opinion. Years ago, Tib gave me and others asking about Cisticolas a lot of patient help. And since he took the trouble to explain his ID, I tried to repay it by paying attention. And hence, I gained enough confidence to sometimes have a stab at some of the commoner east African species. That's all.
But I have no experience of the species which have come up in this thread. After your post, I did spend some time looking around Google photos and in books, so here are a couple of comments as a result of this effort.
The OP bird has (on my screen anyway) a crown and upper back that are the same colour - a slightly rufous brown (although maybe a hint of greyness in the otherwise also rufous brown wings).
Online photos of Chattering (as Butty pointed out) and Bubbling show a grey back and a contrasting rufous crown. Foxy appears to have a rufous crown separated from a brownish back by a clear grey neck, and also to be foxy in colouration underneath. (Also, it's very small, 10cm, and although we can't judge the OP without knowing what the tree is, it gives me the impression of something larger.)
So, the pattern of this bird fits Red-faced better than Chattering and Bubbling, in my opinion, but the colours do not. Online photos show a very distinctive bird with grey crown and back, and light red cheeks with a reddish front above the bill.
However, I think that the OP gape line still has a juvenile look, there is the pale lower mandible, and some of the feathering also looks not yet adult. In which case in may not be obvious what the adult colouring and patterning would be.
The bird that actually struck me as most possible is Whistling, which Andy mentioned but didn't discuss. According to 'Birds of Africa South of the Sahara', it appears to be common across CAR.
From 'Birds of East Africa': '[Adult]: Dull brown crown not contrasting with back.
Immature rusty above and yellow below. White throat (often looks very white when singing), grey sides to neck'. Birds of the World: '
some immatures have bright foxy-red upperparts'. I could only find a few online photos and some of them look rather different from this description (greyish brown crown and back, with a red wing panel), but a couple look as though the OP bird could end up like it (rusty goes to dull brown). Also, Birds of the World says, but doesn't illustrate, '
Race antinorii [the CAR ssp.] is paler and browner above than nominate, with narrow buffy margins of flight-feathers, thus lacking rufous wingpanel', which would account for the online photos I found (i.e. not
antinorii).
So immature Whistling would be my addition to the pot of possibilities.

Anyway that's all I have to offer. Sorry not to be able to help more. Apologies if it's completly off beam.
