The Outer Alster ("Alster" is the name of the river, "Außen" means Outer) represents a large water body located on a migratory bird route within a metropole region. Frequent breeding and feeding birds like Mallard (of course), Great Crested Grebe, Eurasian Coot, Eurasian Moorhen, Great Cormorant or Black-headed Gull are known from many places. Especially during winter half of the year water birds of all kind can be expected. Several species of ducks (including Common Scoter, Greater Scaup, Common Teal), divers (Red-necked Grebe, Black-necked Grebe, Slavonian Grebe (Horned Grebe)), gulls (all common species) and terns ( Black Tern, Common Tern) can be observed with a bit of luck and scope. Even White-tailed Eagle has been seen gliding over. Recorded rarities include Great Skua and White-winged Tern.
The Außenalster is surrounded by a well accessible foot trail and biking lanes. Public transports connects to any side of the water.
