Status of Red-necked Grebe (Prodiceps grisegena), Slavonian Grebe (Prodiceps auritus) and Black-necked Grebe (Prodiceps nigricollis) in Walloon country and Brabant.
Van Der Elst, D.
This study describes the status of the three rare grebes in the Walloon contry and in Brabant. The Red-necked Grebe has become the most common : it is principally sighted from August to March, with peak periods in August and February. The Slavonian Grebe is definitely more of a winter visitor and is the rarest of the three. The Black-necked Grebe is present all the year round and the number of sightings in spring and winter is on the increase, and so is the number of nestbuilding instances.
