“…The 2,100 to 2,800 m altitude range within which the BWE occurred during this study differs from the 1,800 to 2,450 m range previously reported (BirdLife International, 2012;McKay & Coulthard, 1996). This is a cause for concern as not only the forest below 2,000 m a.s.l.…”

“…Bird surveys were conducted in November 2016 to April 2017 which is dry season and species' nesting period (McKay & Coulthard, 1996) in the Kilum and Ijim mountain forests also known as the KICF. The study area is a mosaic of (Solefack, 2017) montane forest-of which the BWE is specialist (Ingram & Nsom Jam, 2007)-montane grassland, and subalpine vegetation.…”

The banded wattle-eye bird species, BWE ( Platysteira laticincta) is rare, endangered, and endemic to the Bamenda Highlands, Western Cameroon. Kilum–Ijim Community Forest is its last stronghold. Little is known about BWE’s distribution and habitat requirements—the present baseline study aimed at reducing this knowledge gap. Bird occurrence—using call playback technique—and vegetation variables were recorded in 50-m radius sampling plots placed in the altitude range 2,100 to 2,800 m. The BWE occurred at 43 (35%) of 123 plots mostly within Kilum sector of the Community Forest, at altitude range 2,168 to 2,707 m. The log-odds of BWE occurrence significantly (a) increased with canopy height, herb relative abundance, bare soil relative abundance, and shrub relative abundance and (b) decreased with altitude and understory height. These results suggest that the BWE may prefer forest areas at lower altitude with more bare ground and denser undergrowth cover. The implications for BWE conservation are discussed.

“…Although no population size figures exist for Mt Mbam for a direct comparison, both sites are considered strongholds for Bannerman's Turaco in the Bamenda highlands with Mt Oku being the first (Njabo and Languy, 2000). According to Forboseh and Ikfuingei (2001) the population of Bannerman's Turaco is in decline based on impending threats such as forest clearance for agriculture, grazing (McKay and Coulthard, 1996), selective extraction of trees for firewood and timber, some of which are fruit trees on which the bird is known to feed. While there are several potential explanatory variables for the differences in species abundance between these sites, this research focuses on investigating the richness and abundance of fruit trees known to serve as food resources to the endangered Bannerman's Turaco as factors contributing to explain the variation in population size of the species between Mt Oku and Mt Mbam.…”

The Endangered Bannerman's Turaco, Tauraco bannermani, is an arboreal montane forest bird, endemic to the Bamenda Highlands and currently facing several threats including selective extraction of trees, some of which are fruit trees on which the bird is known to feed. This study assessed the abundance and species richness of fruit trees known to provide food resources to the Bannerman's Turaco as a factor contributing to the variation in the population size of the bird between Mt Oku and Mt Mbam. 45 plots where systematically established at each site using the point transect method targeting suitable habitats of Bannerman's Turaco. In each plot, we identified and recorded all fruit trees known to provide food resources to Bannerman's Turaco. Diameter at breast height and height of each fruit tree were measured. Data was analysed using Chi-square tests at threshold probability of 5%. Results obtained indicated that fruit trees were significantly more abundant in Mt Oku (n = 531) compared with Mt Mbam (n = 154) (Chisq = 207.49, df = 1 and p = 0.0002). Mt Oku also had a significantly higher fruit tree biomass (Chisq = 5701, df = 1 and p < 0.0002). Similar results were obtained when we controlled for altitude between sites. Of the eight fruit tree species known to provide food resources to Bannerman's Turaco, we recorded seven at Mt Oku (Allophylus bullatus, Ficus sp, Maesa lanceolata, Podocarpus latifolius, Prunus africana, Schefflera abyssinica and Schefflera mannii) and five at Mt Mbam (Allophylus bullatus, Ficus sp, Prunus africana, Schefflera abyssinica and Schefflera mannii). These findings suggest that the significantly higher abundance and biomass of fruit trees contribute to explain the higher population size of Bannerman's Turaco in Mt Oku compared with Mt Mbam. Hence, conservation efforts to protect this endangered bird should take into consideration the protection of fruit trees on which it feeds.
