First, because the avifauna of that area is extremely diversified and plentiful, the knowledge about status, distribution and preservation of birds remains poorly understood, and the scheduled development of Casamance could have a negative effect on both vegetation and fauna.

With this Atlas our goal therefore is to improve the knowledge of the birds of this region in order to be a source of proposals with the authorities for limiting the negative impact of human activities and climate change, for indicating strategic areas for the species with a strong patrimonial value and for supporting the authorities about the establishment of a sustainable ecotourism.


Our own work has been starting since 2007 taking advantage of prolonged stays in Ziguinchor area. In 2012 the idea of achieving an atlas of the birds of Casamance emerged, based on the 333 UTM squares of 10 km aside of the study area. From a sighting pressure as homogeneous as possible on the whole area, the goal is to obtain an accurate map of the distribution of the species and to know more about their biological status and preservation. At the end of 2016 about half the 333 squares have been prospected.

The avifauna of Casamance is rich of at least 531 species. 318 are potentially breeding, more than 115 are palearctic migrants and the others are more or less episodic vagrants. A rich diversity that underlines the sheer variety of habitats and the presence of well-kept Guinean forests.

At the end of 2016 the database contains about 12,000 data lines for 417 species.


For each species the following information appears : m: number of UTM squares with data. By clicking on the name of the species the squares UTM with data are displayed.


For each UTM square the following information appears : d: number of data / e: total number of species / np: number of species with probable breeding / nc: number of species with confirmed breeding / h: number of wintering species. While hovering over a square the list of species is displayed.

A stay in the area may be rewarding for listing birds whatever the month since species are breeding all year round. Nevertheless the period from April to November is the most favourable, with the wet season stretching out from June till October.
