Description
During late April and early May hundreds of Χωραφόχηνα and Tundra Bean Goose are staging at lake Ostträsket. Most other species of geese also occurr in smaller numbers, as well as Αγριόκυκνος and (Ευρωπαϊκός) Γερανός. Until a few decades Νανόχηνα was regular here but it is nowadays very rare. Dabbling ducks may stay in good numbers, especially (Ευρωπαϊκό) Κιρκίρι and Πρασινοκέφαλη Πάπια. Λυροπετεινός are lekking on the fields around Tällåsen.
There are plenty of (Ευρωπαϊκός) Γερανός also in August and September (up till several thousands). Σταχτόχηνα is the most numerous goose species during the autumn. Raptors like (Ευρωπαϊκός) Θαλασσαετός, Χειμωνόκιρκος, Νανογέρακο or Πετρίτης are regular. Στεπόκιρκος is more or less annual. Often interesting passerines feed on the fields, as Lapland Bunting or Χιονοτσίχλονο.
Though a visit may prove nice at any time of year, the summer months yield less birds. The amount of breeding birds in the lake is low, but it is used by feeding Νανόγλαρος, and Δεντρογέρακο and Ψαραετός are not uncommon.

Access
The only practical way to access Ostträsket is by Tällåsen in the western part. There is an informal vantage point in the village, as well as a birding tower by the meadows. To see (Ευρωπαϊκός) Γερανός or geese during the days you may want to drive around on the public roads between Drängsmark, Kågegården and Kåge.

The geese and (Ευρωπαϊκός) Γερανός usually spend the night on the lake's ice or in the flooded meadows, and fly to the fields when sun rises. They tend to feed in a large area around the villages of Drängsmark and Kåge, but often near the lake at Tällåsen which is also the best spot to see them flying to and from the night quarters. The best time to visit is about April 20th until May 5th, or in autumn around September 1st-20th.
