3.4 Biome-restricted species: Afromontane<br />
biome<br />
The survey also discovered a significant component <strong>of</strong><br />
afro-montane avifauna. Altoge<strong>the</strong>r, 28 afro-montane<br />
species were recorded (Appendix 1), more than<br />
previously believed existed <strong>in</strong> this area. For many<br />
species, <strong>the</strong>ir occurrence at <strong>Takamanda</strong> significantly<br />
extends <strong>the</strong>ir known range <strong>in</strong> Cameroon; for some,<br />
<strong>in</strong>clud<strong>in</strong>g Kupeornis gilberti and Poliolais lopezi, <strong>the</strong><br />
closest known records <strong>in</strong> Cameroon are more than 100<br />
km distant. Most montane species at <strong>Takamanda</strong> are<br />
known from <strong>the</strong> nearby Obudu Plateau <strong>in</strong> Nigeria<br />
(Fishpool and Evans 2001) however, so <strong>the</strong>ir presence is<br />
not totally unexpected.<br />
3.5 Biome-restricted species: lowland<br />
(Gu<strong>in</strong>eo-Congolian) forest biome<br />
The occurrence <strong>of</strong> 139 species restricted to <strong>the</strong> Gu<strong>in</strong>eo-<br />
Congolian forest (Appendix 1), although expected, is<br />
<strong>Takamanda</strong>: <strong>the</strong> Biodiversity <strong>of</strong> an African Ra<strong>in</strong>forest<br />
particularly <strong>in</strong>terest<strong>in</strong>g and confirms that <strong>Takamanda</strong><br />
Forest Reserve holds a vast component <strong>of</strong> lowland forest<br />
avifauna. Protection <strong>of</strong> <strong>the</strong> Reserve would preserve a<br />
representative sample <strong>of</strong> <strong>the</strong> lowland forest avifauna.<br />
It should be noted that two species—Sun Lark<br />
Galerida modesta and <strong>the</strong> Bush Petronia Petronia<br />
dentate—which are more typical <strong>of</strong> Gu<strong>in</strong>ean savannas<br />
were recorded <strong>in</strong> <strong>the</strong> grasslands.<br />
3.6 O<strong>the</strong>r <strong>in</strong>terest<strong>in</strong>g records<br />
The survey recorded two species that are new to<br />
Cameroon—Ussher’s Flycatcher Muscicapa ussheri,<br />
observed twice (once <strong>in</strong> <strong>the</strong> vic<strong>in</strong>ity <strong>of</strong> its close relative<br />
Sooty Flycatcher Muscicapa <strong>in</strong>fuscate) and Grey-headed<br />
Bristlebill Bleda canicapilla, which was captured <strong>in</strong> mist<br />
nets on two occasions. The discovery <strong>of</strong> Ussher’s<br />
Flycatcher was not totally unexpected, given that <strong>the</strong>re<br />
are records <strong>of</strong> this bird about 50 km from <strong>Takamanda</strong> <strong>in</strong><br />
eastern Nigeria (Elgood 1994). Grey-headed Bristlebill<br />
reaches its eastern limit at <strong>the</strong> Cameroon-Nigeria border.<br />
O<strong>the</strong>r species <strong>of</strong> <strong>in</strong>terest <strong>in</strong>clude Tufted Duck Aythya<br />
fuligula (Bobo et al. 2000), recorded on <strong>the</strong> Magbe River<br />
with o<strong>the</strong>r aquatic species, and Capuch<strong>in</strong> Babbler<br />
Phyllanthus atripennis, recorded at Obonyi 1 and<br />
Kepani.<br />
On four occasions, we recorded Kemp’s Longbill<br />
Macrosphenus kempi, a West African species that is<br />
sympatric with Yellow Longbill Macrosphenus flavicans<br />
as <strong>the</strong> two species meet along <strong>the</strong> Cameroon-Nigeria<br />
border. The only o<strong>the</strong>r site for Kemp’s Longbill <strong>in</strong><br />
Cameroon is Korup National Park (Rodewald and<br />
Bowden 1995).<br />
An <strong>in</strong>terest<strong>in</strong>g record from a biogeographical<br />
perspective is <strong>the</strong> presence <strong>of</strong> both Red-cheeked Wattleeye<br />
Dyaphorophyia blisseti and Black-necked Wattleeye<br />
Dyaphorophyia chalybea. These two closely related<br />
species replace each o<strong>the</strong>r: Red-cheeked Wattle-eye is a<br />
West African species reach<strong>in</strong>g its eastern limit <strong>in</strong><br />
Cameroon, with records around Mt. Cameroon and<br />
Kumba (Louette 1981). The two species were not
