1 Introduction Birds of Takamanda Forest Reserve, Cameroon Marc Languy and Francis Njie Motombe Cameroon, stretching from the Atlantic Ocean to Lake Chad, boasts a varied topography and many habitats. As a result, the avifauna is particularly rich; 928 species have been recorded to date (Languy et al. in press). The Cameroon government and international organizations realize the need to document and protect the country’s biological diversity, and a number of field surveys were conducted from 1999 to 2001 to identify sites of high biological—particularly ornithological—value in Cameroon through the Important Bird Area process, coordinated by BirdLife International and implemented by the Cameroon Ornithological Club (COC). Still, the avifauna of Cameroon is poorly known when compared to countries in eastern and southern Africa as well as some West African countries. During a national workshop organized by BirdLife International and the COC in September 1998, Cameroon’s Takamanda region and the area west and north of Mamfe were identified as areas in need of field surveys (COC 1998). Prior to this study, only a brief survey undertaken by World Wildlife Fund in 1988 (Thomas et al. 1989) had been completed in Takamanda vicinity, recording fewer than 50 species. However, even that short list indicated the presence of three sub-montane species—Blackcapped Woodland Warbler Phylloscopus herberti, Bocage’s Akalat Sheppardia bocagei, and Crossley’s Ground-thrush Zoothera crossleyi. This sub-montane component, together with vast areas of lowland forest, point to potentially high bird diversity at Takamanda and, possibly, rare or even threatened species. In recognition of that potential, COC and BirdLife International proposed in 1998 that Takamanda be considered as an Important Bird Area; that is, a site of special conservation value for birds. IBAs are selected using internationally recognized objective, scientific criteria. A portion of Takamanda is adjacent to Obudu Plateau in Nigeria and thus is part of the Cameroon- Nigeria Mountain range that stretches from Bioko to Tchabal Mababo and Tchabal Ngandaba and includes Mt. Cameroon, Rumpi Hills, Mt. Nlonako, Bakossi Mountains, Mt. Kupé, Mt. Manenguba, and Bamenda Highlands. This mountain range is well known for its high degree of endemism in many taxa. For example, 24 species of birds are restricted to this mountain range. While birds on the ridge are relatively well known, Takamanda is an outlier that deserves attention. 2 Methods Chapter 7 The discovery of three sub-montane bird species by WWF in 1988 prompted us to focus on sampling the highest altitudes of the Takamanda Reserve and check whether afro-montane species occur. At the same time, we recognized that most of the Reserve is covered by lowland forest (see Sunderland et al. this volume), and a special effort was made to cover this biome to the extent possible. Our primary method of investigation was to walk slowly in the forest and to remain sitting quietly at regular intervals to record as many birds as possible, using binoculars. Fourteen sites were sampled in this manner (Table 1 and Figure 1), and many species were identified by their calls or songs. We incorporated the use of field guides, including plates from Borrow and Demey (2002), and color copies of selected plates from Birds of Africa. See Appendix 1 for a list of the species we recorded.
