Waterfowl in Large Numbers

The waterfowl population in Vanhankaupunginlahti bay is impressive and quite easy to observe. Most of the water birds are relatively large and colourful, and they readily swim in the open water. In addition, many of the species, for example the great crested grebe and the common goldeneye, have very distinct coupling displays that can be admired from the bird watching towers.

Among the most visible species is also the large-sized mute swan. Swans nest regularly at Vanhankaupunginlahti bay and can often be seen taking their young for a swim. Other common nesting waterfowl are wigeons, teals, mallards, garganeys and Northern shovelers. Common goldeneyes and goosanders have begun to nest in the nesting-boxes during recent years in ever growing numbers.

In spring, when large flocks of waterfowl stop at Vanhankaupunginlahti bay on their way to the nesting areas further north, a great variety of species can bee seen. At that time, birdwatchers at Vanhankaupunginlahti bay may spot species like the smew, the Northern pintail and the gadwall, as well as the more occasional red-necked grebe and the Slavonian grebe. Geese nesting in the Siberian tundra are also visible in Vanhankaupunginlahti bay. Late May, the winds permitting, birdwatchers in Viikki may witness barnacle geese flying north in flocks of thousands. In addition, barnacle geese nesting on nearby islands can nowadays be seen moving around with their young and grazing the Viikki fields in autumn.
