Exchanges with the various actors of the site we note that in reference, the knowledge in avifaunique of the employees (on site) is rather limited even more for the knowledge on the biodiversity in general. Some species are known in the local language; this is the case for turtle doves, commonly known in the Fon "houélé" local language, which practically everyone knows. It must be said that this lack of knowledge did not prevent them from carrying out isolated actions such as prohibiting access of the site to local communities external to the site and therefore at the same time to local hunters.
From these exchanges with employees, we also note that in terms of abundance there are more species than before because according to them said the vegetation was more luxuriant in the initial state.
It was also noted that none of the employees are hunting birds at the Fongba quarry site. But the activity of explosion sometimes makes fall of the niches of birds. This state of affairs would cause the departure to other places of the birds and the tremors engendered by the explosion could be at the base of the fall of the niches. It is therefore important to find a way to make the explosions, which are essential for the operation of the quarry in birds, less harmful.
But the employees were all unanimous on the fact that the abandoned and water-filled quarry holes are favorable for the presence of some of the duck family and the observations made (to the description given).
