It lies within the Sahel zone and corresponds to "Zone ecologique 4" of Giraudoux et al. (1988). This part of Niger has a single rainy season from late May to early October with an average annual precipitation of c. 340 mm. The Komadougou Yobe River forms the southern boundary and is the border with Nigeria. Maine-Soroa, Diffa and Nguigmi are the only towns and most villages are found along the river and the former shore of Lake Chad.
250 bird species were recorded in 2008. Otherwise very little had been published on the birds of southeast Niger.The observations summarized by Giraudoux et al. (1988) were mainly from the 1970s, with few from the 1920s by Buchannan (Harterrt 1921, Bates 1933) and from the 1940s by Rousseelot (1947).
