Descrição
The lake itself has a rather artificial and steep shoreline and is heavily used by water sports enthusiasts, making it attractive for birders mostly during winter months when northern waterfowl species can be frequently seen. Zarro-comum and Zarro-negrinha are common, Merganso-grande and Pato-olho-d'ouro quite rare nowadays. Guincho-comum occurs in large numbers during winter, and occasionally rarities can be found among the more common duck and gull species (Records include Papa-ratos, Socó-taquari, Zarro-de-colar, Gaivota-hiperbórea and Gaivota de Bonaparte). Mergulhão-de-crista is a common breeder and the lake offers great observation possibilites of the species' courtship behaviour.
The restored wetland along the river Aa southwest of the lake offers an interesting mixture of reedbeds and Salix shrub, providing breeding habitat for rouxinol-dos-caniços, Felosa-palustre, Escrevedeira-dos-caniços and Pisco-de-peito-azul (rare). Other breeding species include Mergulhão-pequeno, Frisada, Cuco-canoro, Rouxinol-comum, Guarda-rios-comum, Ostraceiro and Mocho-galego (nearby). Cegonha-branca uses the area to forage and during migration time a variety of waders and ducks can be seen.
