The aim of this study is to contribute to better management
of the avian fauna in the Congo Basin, and in particular in the greater Mbam
area of Cameroon. Biodiversity is the wealth constituted by all forms of life
on earth. It can be considered at three interdependent levels: genetic,
specific and ecosystemic. To inventory parrots, determine their relationship
with vegetation and the threats they face, 10 transects in parallel lines
measuring 2 km long and spaced 30 km apart were randomly selected in the study
area (4°10 - 5°20 N; 10°30 - 11°50 E), consisting of the Mbam and Inoubou site,
which is predominantly savannah, and the Mbam and Kim site, which is
predominantly forest. The transects were walked simultaneously on 02 / 02 /
2011 (dry season) between 6.30 a.m and 8.30 a.m, then on 20 / 08 / 2011 (rainy
season) at the same time, by 10 teams of 3 people equipped with binoculars. 500
people were interviewed to obtain additional information on the parrots'
activities and uses. In the rainy season, Grey Red-tailed Parrots (GRTP)
identified in the forests and savannahs of the Mbam and Inoubou site with a
relative abundance (RA) of 3.97x103 and in the forests of the Mbam and Kim site
(RA = 5.00x103), are less numerous than Red-headed Lovebirds (RHL) observed only
in the savannahs of the Mbam and Inoubou site (RA = 1.94x104), and more
abundant than Senegal Green Parrots (SGP) which colonise both the forests and
savannahs of the Mbam and Kim site (RA = 3.78x103). All these parrots (AR =
3.21x104) migrate during the dry season. The absence of parrots in the study
area during the long dry season is due to the fact that the food resources
available are insufficient in quantity and nutritional quality to maintain
their populations during this arid period, forcing them to migrate in order to
survive. The parrots use 26 plant species belonging to 20 families. The Mbam
and Inoubou site uses a higher biodiversity of plants. In the Mbam et Kim site,
Melicia excelsa and Terminalia superba are heavily utilized by GRTP and SGP for
perching, roosting, and breeding. However, at the same time, logging is heavily
deforesting these species, endangering their habitats. Poaching is another
hazard to the GRTP.
