The Biebrza Valley is also a haven for diverse fauna, with the moose – the “king” of the marshes – at the forefront, which can often be seen from the high banks of the valley. Biebrza is also a key breeding area for many bird species in Poland and Europe; 246 species of birds have been recorded in the park, of which 186 are breeding species. The village of Brzostowo and the viewing tower in Burzyn, from where there is a breathtaking panorama of the Biebrza Valley, are particularly popular with tourists.
