Description
The Blankensee can be overlooked best from a boardwalk near the village of the same name. Close views of Bıyıklı baştankara and Saz Kamışçını, with luck also Çulhakuşu, are possible from the boardwalk (no scope needed). Balaban is often seen flying out of the reeds near the boardwalk, especially in winter. An occupied Balık kartalı nest can be seen from the boardwalk in summer.
Thousands of ducks and geese are on the lake in winter. Sütlabi, Büyük tarakdiş and Altıngöz give good views. Others are Elmabaş patka, Tepeli patka, Fiyu and Boz ördek. Akkuyruklu kartal is regularly seen. The most common large gull is Gümüş martı.
May is the month for Kara sumru. With luck you can get Akkanatlı sumru and Bıyıklı Sumru, too. Other good birds in spring are Karaboyunlu batağan Karaboyunlu bataðan, Kilkuyruk and big flocks of swallows.
Walking through the village (Küçük iskete, Leylek), make sure to have a look for Yalıçapkını along the river Nieplitz.
On the walk to the tower in the north you pass the small lake Seechen (diminutive of lake "See"). Chances are good for Altıngöz, Küçük batağan and Kızılboyunlu batağan. From the tower you overlook the wetlands of the Ungeheuerwiesen. A breeding Balık kartalı, Kızkuşu, Su çulluğu and with luck İbibik can be seen. In winter Turna, Altın yağmurcun and northern geese are typical species. Büyük örümcekkuşu is regurlarly seen in the open winter landscape.
