Badis is a PhD at the University of Science and Technology Houari Boumediene Algiers (Algeria), interested in animal population dynamics and behavioral ecology. Most of his works were focused on ornithology and herpetology, he is fascinated by shorebirds because their populations are poorly known in Algeria. He starts to study two species of shorebirds (Little ringed plover and Black-winged Stilt), his work with the species will includes nesting and breeding ecology in tow sites. Algeria harbor large marshes and swamps. Currently, their number decrease because of majority were victims of need in construction and agriculture.

Among these exceptional ecosystems, urban and peri-urban waterbodies remain poorly studied and poorly documented.

First site Boussedra’s marsh is a pond located in far north-eastern country. It plays a key role during the migration and reproduction of many bird species (notably vulnerable ones). The 2nd site is a Ramsar Reserve of Reghaia’s Lake, located 30 km to the east of Algiers, close to the Mediterranean coast.
