Grèbe castagneux ( Tachybaptus ruficollis )

            Avec  25 à 29 cm de long pour 130 à 230 grammes, le Grèbe castagneux (Tachybaptus ruficollis) est le plus petit grèbe d'Europe. En plumage nuptial, il est facilement identifiable par son plumage très sombre, ses joues et les côtés de son cou châtain qui lui ont valu son qualificatif de « castagneux » (la castagne étant le nom de la châtaigne en Gascogne) et une marque blanc crème à la base du bec. Son plumage internuptial, à partir de la fin de l'été,  est plus terne.
En période de reproduction, le Grèbe castagneux se tient le plus souvent dans la végétation aquatique où il chasse et pêche des insectes aquatiques et leurs larves, des mollusques et de petits poissons, capturés essentiellement à moins de 1 mètre de profondeur.

With 25 to 29 cm long for 130 to 230 grams, the Little Grebe (Tachybaptus ruficollis) is the smallest grebe in Europe. In nuptial plumage, it is easily identifiable by its very dark plumage, its cheeks and the sides of its chestnut neck which have earned it the qualifier of "castagneux" (the name of the castagne is the name of the chestnut in Gascony) and a creamy white mark at the base of the beak. His internuptial plumage, from the end of the summer, is duller.
In breeding season, the Little Grebe occurs most often in the aquatic vegetation where it hunts and fishes aquatic insects and their larvae, molluscs and small fish, caught mainly within 1 meter of depth.
