Descrição
Built in 2004, the retention basin undergoes an ongoing succession and change of habitat types. After loosing it's open character through the establishment of willow, alder and reed stands, it is now a very diverse, mostly flooded area of open water, reed beds and young alluvial forest. The construction activity of Eurasian Beavers alters the landscape regularly and creates more open habitats, where the beaver fells the young trees.
The basin holds significant numbers of different warbler species such as Felosa-dos-juncos, rouxinol-dos-caniços, Rouxinol-grande-dos-caniços, Felosa-palustre, Felosa-malhada and Felosa-unicolor and also Cartaxo-comum and Tartaranhão-ruivo-dos-pauis. Breeding has been documented for Garça-pequena and Socó-taquari. Faisão, Perdiz-cinzenta, Frango-d'água, Rola-comum and Escrevedeira-dos-caniços are regular or abundant breeding birds. Big flocks of Estorninho-malhado use the reed beds for roosting at night, so by the end of May, it is worth to check them for Estorinho-rosado. Andorinha-das-chaminés also sleeps communally in the reed and attacks of Gavião da Europa and Ógea can be seen regularly at dusk.
Overflying birds of prey, which can be seen quite regularly, include Águia-imperial-oriental, Águia-rabalva, Falcão-sacre and Tartaranhão-caçador. On migration, the area provides roosting habitat for bigger numbers of songbird migrants and surely has potential to produce rarity sightings as well. Alvéola-citrina has already been recorded, but the area is not covered well by birders, so most rarities surely pass unnoticed.
Winter visitors include the regular species Tartaranhão-azulado and Búteo-calçado, but also a record of Abetouro-comum.
Detalhes
Acesso
Access is easiest by car, but public busses service Roseldorf station which is approx. a 10 minute walk to the edge of the basin. Please follow the cirular route (2 km) and do not leave the track in order to not disturb any wildlife. It is definitely not recommended to enter the basin itself, as it is flooded in huge areas anyways. Click on the P in the map for directions.
