Springtime for example brings to the Biebrza Wetlands a spectacular show of bird migration. Such a phenomenon attracts an international community of birdwatchers. It is a kind of a polish "photo - safari". 270 species of birds have been documented in the Biebrza valley, 180 of those breed here permanently. The fauna is diverse and dominated by water and mud birds with some extremely rare species. Some of the threatened birds that are found here: whooper swan, widgeon, great snipe, ruff, white backed woodpecker, white winged tern, black stork, greater and lesser spotted eagles, eagle owl and white tailed eagle just to name a few.

Among bushes and swamps lives the king of Biebrza Marshes, the elk. Even though the elk were almost pushed to extinction in other parts of Poland, here in the extensive and hardly accessible by man Red Marsh reserve, the elk have survived. Our lady, the queen of Biebrza Marshes is the sleek and elegant red deer. Crowned prince of these marshes, the wolf is a fierce and deadly carnivore, this label can be proved with the trail of skeletons it leaves in its wake. Finally, the court jester of Biebrza is the free wheeling otter, this mischievous animal can be observed from long distances frolicking along the waters of Biebrza.

One of the most picturesque places in all of Poland, the Biebrza Wetlands has something for everyone. Apart from watching the birds you can hound the elk and perhaps you manage to see a black spot between the trees. The bicycle and foot expeditions through the Biebrza Valley abound in many sensational feelings.
Having such outstanding natural and landscape values it was decided in 1993 to establish the biggest and highest level of nature protection in Poland. With a total area of 59 233 ha, it has become the largest of the Polish national parks. The Park includes 15 547 ha of forests, 18 182 ha of agricultural land, and 25 494 ha of wetlands - the most valuable habitats of the park - the famous Biebrza marshes. The area of 3 936 ha is under strict protection ha including the Czerwone Bagno or Red Bog at the Grzędy Forest District. Unique in Europe for its marshes and peat lands, as well as its highly diversified fauna, especially birds- the Park was designated as a wetland site for migratory birds of global significance and since 1995 is under the protection of the RAMSAR Convention.
