Other comments: Fer numbers from five to nine have been replaced by from Arabic numerals, they might use Arabic numeral system more often now. There are some confusions about certain language names in this area (as in many areas I guess!).
Fer is in fact the genuine name of "Kara" of Birao/Central African Republic. So it is not unclassified as mentioned by Ethnologue but clearly a member of the Bongo-Bagirmi languages, more closely related to the Gula languages or dialects (see P. Nougayrol).
Furu is not an alternate name for Fer (nor for Kresh as sometimes mentioned). Furu is the name of a group living in D.R.C., south of the Oubangui river. Their language is apparently quite close (a dialectal variant ?) to that of the Bagiro, living not far from them, on the other side of the Oubangui, i.e. in C.A.R. Indeed the Bagiro claim to be an offshot of the Furu group, that they probably left some 200 years ago. Furu-Bagiro is clearly another member of Bongo-Bagirmi, more specifically belonging to "Sara proper". (The own name of Bagiro is Gbaya, which is also the name of a Kresh section, hence the frequent but erroneous identification of Furu-Bagiro with Kresh).
Maybe you could get some more information (unfortunately in French only!) in the Introduction to the Comparative-Historical Lexicon of Sara-Bongo-Bagirmi Languages at
