This year Žuvintas is louder. There are many more waterbirds trolls, cries, gags than in previous years, as this summer will be probably the most successful for many of the species breeding here in the last decade.

Hatching waterfowl surveys have already been carried out, giving the good news that the abundance of typical lake birds is slowly recovering. Great Crested Grebes in Žuvintas have made 27 nests, Black Terns as many as 135 - these two species have not migrated so abundantly for 30 years, and the nests of 57 Common Terns in Lake Žuvintas have not been detected since the beginning of regular surveys in 1966. Dozens of pairs of Common Pochards, Mallards, Eurasian Cranes, and several dozen Greylag Gooses crossed the lake.

Interestingly, most of these birds nested in specially supervised areas of the lake. In the spring of this year, the reserve management received a special amphibian for cutting aquatic vegetation. Before the start of the nest rotation time, we tested this technique by cutting just a dozen acres of old sandpipers. The results turned out to be very excellent. All Black-headed Gulls, the vast majority of grebes and terns, immediately moved to areas suitable for migration. What's more, several pairs of wetland birds flew into the lake to cross the lake - redshanks, pemps.

This summer, according to the nature management plan, it is planned to cut down even a few hectares of bulrushes and reeds. This is very important for maintaining more open breeding areas in the lake. Such a practice, especially in winter, to cut and remove dried bulrushes and reeds in Žuvintas has been known since ancient times, but was later forgotten and no longer used. We have a unique opportunity not only to try a new nature management tool, but also to be happy with its results.
