Grèbe castagneux Tachybaptus ruficollis

Le Grèbe castagneux est le plus petit des membres de la famille des grèbes, d'où son nom (qui le compare à la taille ou la couleur d'une châtaigne) et son synonyme vernaculaire de Petit Grèbe. C'est aussi le seul grèbe d’Europe à pondre régulièrement deux fois par an.
Oiseaux discrets, ils s’installent sur n’importe quel lac, étang, mare ou marais possédant une végétation assez dense sur ses rives.
Le Grèbe castagneux a une apparence replète due à son derrière arrondi, caractéristique renforcée par l’habitude qu’a ce grèbe d’ébouriffer les plumes de son croupion. Son aspect en « boule de duvet » donne souvent l’impression qu’il flotte comme un bouchon.
De fait, à part lors de la nidification, cet oiseau est rarement vu à terre.
