Abstract
The spatial distribution of the bird community of the Koko urban dam and its surroundings (Korhogo; Côte d’Ivoire), was studied for the first time from February 2016 to January 2017. The inventory method consisted of a slow walk, punctuated by a 15-minute stop, along the banks of the dam in order to test the effect of habitats on the distribution of the bird community. A total of 1,613 birds, divided into 63 species belonging to 32 families and grouped into 14 orders, were inventoried. The Passeriformes order and the Ardeidae family were the best represented. Diversity was highest in the wooded savannah and the prairie. Migratory species were most numerous in the water while resident species were best represented in the prairie and wooded savannah. The distribution of bird species has shown that prairie and tree savannah have been the preferred habitats of this community. Therefore, these refuge habitats must be preserved in light of the anthropogenic pressures experienced by this ecosystem, which could pose a threat to this community.
Introduction
Human activities exert pressure on natural ecosystems with the consequence of losing biodiversity (Khaffou et al., 2013; Konan et al., 2014). For sustainable and rational ecosystems management, knowledge of communities, habitat specificities, population change and threats must be taken into account (Conservation International, 2001). Birds have a variety of ecological, pharmacological and conservation interests (Benayas et al., 2017; Platel and Ravel, 2019). Despite these importances, little data is available on their habitats. Habitats are refuges in response to different pressures. Their destruction would lead to downsizing and hence their disappearance (Ahmad and Bhat, 2017; Platel and Ravel, 2019). Therefore, they are essential in the implementation of conservation strategies.
Wetlands are fertile and productive ecosystems (Platel and Ravel, 2019). These environments provide various ecosystem services as well as water on which plant and animal organisms depend for their survival. Man benefits from this in the context of aggro-pastoral activities (Odoukpé et al., 2014). These ecosystems are home to variety of habitats with high food resources availability and are therefore home to a high diversity of avifauna (Patole et al., 2009; Ahmad and Bhat, 2017; Platel and Ravel, 2019). Indeed, these wetlands are sites of nutrition, wintering and breeding for many migratory and resident waterbird species, some of which are on the International Union for Conservation of Nature's Red List (El Agbani and Dakki, 2005; Borrow and Demey, 2008; Yaokokoré-Béibro, 2010). Wetland birds would therefore provide essential information on the health and conservation status of these ecosystems in order to determine their conservation value (Kumar and Gupta, 2009). However, these fragile ecosystems, with high ecological and conservation potential are threatened with disappearance due to anthropogenic activities, with the consequent loss of biodiversity (Williams, 1993; Brooks et al., 2007; Ahmad and Bhat, 2017).
In Côte d'Ivoire, work on avifauna was mainly carried out in forest and urban areas, in the southern part of the country and incidentally in the centre and west (Kouadio et al., 2014; Odoukpé et al., 2014; Konan et al., 2015; Yaokokoré-Béibro et al., 2015 a, b; Zéan et al., 2018). Ornithological studies of wetlands are few and have been concentrated in Grand-Bassam, Yamoussoukro and incidentally in Abidjan (Odoukpé et al., 2014; Konan et al., 2015; Yaokokoré-Béibro et al., 2015 a, b). The north of the country is home to various agro-pastoral dams, which have been the subject of very few studies, relating to global and seasonal variations in avifauna (Niamien et al., 2019 a, b). No studies have focused on spatial variations. To fill this information gap, we conducted this study. It is a contribution to a better knowledge of birds ecology in order to ensure sustainable and rational management. It specifically aims to (i) inventory the birds of the Koko urban dam and (ii) examine how bird communities use their habitats.
